Comparison of Ray Tracing Through Ionospheric Models
A comparison of ray tracing predictions for transionospheric electromagnetic wave refraction and group delays through ionospheric models is presented. Impacted applications include over-the-horizon RADAR, high frequency communications, direction finding, and satellite communications. The ionospheric models used are version 2.1 of Utah State University's Global Assimilation of Ionospheric Measurements (USU GAIM) model and the 2001 version of the International Reference Ionosphere (IRI) model. In order to provide ray tracing results applicable to satellite communications for satellites at geosynchronous orbit (GEO), a third ionospheric model is used to extend the sub-2000-km USU GAIM and IRI ionospheric specifications to 36540 km in altitude. The third model is based on an assumption of diffusive equilibrium for ion species above 2000 km. The ray-tracing code used is an updated implementation of the Jones-Stephenson ray-tracing algorithm provided by L. J. Nickisch and Mark A. Hausman. Ray-tracing predictions of signal refraction and group delay are given for paths between Goldstone Deep Space Observatory near Barstow, California, and the PanAmSat Galaxy 1R satellite. Results are given for varying frequency between 11MHz to 1GHz, varying time of day between 0600 and 1700 Pacific Standard Time on 1 November 2004, and varying signal transmission elevation angle.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Characteristics of Two-Dimensional Triangular and Three-Dimensional Face-Centered-Cubic Photonic Crystals
Photonic crystals (PhC's) are periodic structures of differing dielectrics that create a photonic band gap (PBG). A PBG, in turn, inhibits the propagation of electromagnetic waves of a speci c frequency range. This thesis focuses on the fabricationand characterization of triangular-structured, two-dimensional PhC's with a PBG de-signed for visible wavelengths and with applications in visible integrated photonicsystems. A three-dimensional PhC with a PBG in the infrared is also studied for itscharacteristics in regard to its PBG.The two-dimensional fabrication processes pursued were: focused ion beam, electron beam lithography and holographic photo-polymerization/lithography. Thefabrication techniques and materials used to create the PhC in part determined thecharacterization technique required to investigate the PBG. Characterization tech-niques include: the coupling of a beam by means of a prism into a wave-guidingmedium in which the PhC has been fabricated, Fourier transform infrared spectrom-eter, spectrophotometer, and edge ring techniques. Analysis of the transmission andre-ectance properties of a PhC for various incident angles (within the two dimen-sional plane of the PhC) con rms the presence of a PBG. The design of the PhC wasbased on a program created to display gap maps for triangular structures. The PBGof the structure, designed from the gap maps, was modeled using another programcreated to display band diagrams for triangular structures. Finite di erence timedomain (FDTD) software was then applied to compare the experimental results withthe modeling and simulation of the PhC fabricated. Two di erent FDTD softwareswere also evaluated.The three-dimensional PhC sample obtained was successfully tested with theFourier transform infrared spectrometer and the spectrophotometer.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Passive Ranging Using Atmospheric Oxygen Absorption Spectra
The depth of absorption bands in observed spectra of distant, bright sources can be used to estimate range to the source. Previous efforts in this area have relied on measuring infrared CO2 bands, with disappointing results. A novel approach is presented here and demonstrated using observations of the O2 absorption band near 762 nm. Oxygen was chosen because its concentration is more stable and predictable than CO2 or H2O, and this band is spectrally isolated from other atmospheric bands, which enables direct estimation of absorption. Range is estimated by comparing observed values of band-average absorption, A, against curves derived from either historical data or model predictions. Curves are based on fitting a random band model to the data, which reduces average range error by 67% compared to the Beer's Law model used in previous work. An original model is presented based on a traditional random band model, modified to account for variations in absorber concentration over long, inhomogeneous paths. This mod- ification further reduces error by over 50% in short-range experiments, and can be used in conjunction with any band model. A static rocket motor test was observed using a Bomem MR-254 Fourier trans- form spectrometer at a range of 2.8 km. In this case, observed values of A were com- pared against data simulated using FASCODE, a validated atmospheric transport model. Detailed atmospheric soundings were not required; a standard atmosphere was used, and a simple correction, based on published meteorology data, is presented. The resulting range estimate was accurate to within 0.5% (14 m). Similar accuracy was also achieved at shorter ranges using a lamp as a surrogate target. Long-range performance is predicted by using FASCODE and theoretical mod- els to extrapolate observed short-range performance. Range error of 5% or less is predicted at ranges up to 400 km for a representative target.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Phasing a Dual Optical Path System Using an Optical Fiber as a Phase Conjugate Mirror
Phase conjugation properties of stimulated Brillouin scattering (SBS) in a short multimode fiber have been investigated with an eye towards its application for a multi-channel double pass master oscillator power amplifier (MOPA) system. In particular, properties of the SBS beam to compensate for the axial and transverse phase distortion between individual channels in a multi-channel amplifier system were studied. Two optical paths were created by covering half of the laser beam with a microscope slide, and also by spatially splitting the wavefronts with a 4 prism set-up. The Stokes beams that traversed the same optical paths as the pump beams were shown to compensate the phase distortion introduced by the different optical paths.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Measuring Dispersion in Laser Cavity Mirrors Using White-Light Interferometry
Terahertz radiation is an emerging field that has far reaching applications. There is a need for portable and affordable terahertz sources that may be used for detection of structural weaknesses in aerospace composites. One possibility for terahertz generation is a femtosecond Cr: LiSAF laser. However, controlling intracavity dispersion is necessary in order to get the ultrashort pulses needed to generate terahertz radiation. This research measures dispersion of the chirped femtosecond intracavity mirrors by employing white-light interferometry and explains the theory behind the curve-fitting process used to calculate dispersion. To compensate for the narrow reflectivity band of the mirrors, a CaF2 (calcium fluoride) window was used to increase the number of spectral fringes in the interferogram.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Filtered Rayleigh Scattering Measurements in a Buoyant Flowfield
Filtered Rayleigh Scattering (FRS) is a non-intrusive technique for studying flowfields. It utilizes a narrow linewidth laser, an absorption filter, and a detector. Molecular scattering provides the signal to the camera, and the difference in molecular cross section can be used to discriminate between unmixed gaseous components. The focus of this research is to document the behavior of a horizontal buoyant jet using FRS. A helium jet of precisely controlled mass flow rate is injected into a standard room temperature environment, and FRS provides the means to measure its core trajectory and mixing rate. Trajectory analysis, conducted with consideration of the Reynolds number and Grashof number, can be used to compare these results to the literature. A significant portion of the study was dedicated to measuring the rate at which FRS data can be acquired with a continuous wave laser. Additionally, mixing patterns for the buoyant jet were collected and indicate that core low-density fluid is expelled into the ambient region in a striking manner under certain conditions. Although such an expulsion of core low-density fluid has been noted in the literature, it has generally been associated only with an upward direction. This was observed at a Reynolds number of 238. However, at a Reynolds number of 667, the jet appears to take on features of jets subjected to an exaggerated form of helical mode excitation. The physics behind this phenomena requires additional study.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Continued Optical Sensor Operations in a Laser Environment
The U.S. and other industrialized nations are conducting research and development of directed energy applications, including High-energy Lasers (HEL) and Low-energy Lasers (LEL). While HEL will likely have military applications in Ballistic Missile Defense (BMD), Counter-Air, Counter-Space, and Counter-Intelligence, Surveillance, and Reconnaissance (ISR), HEL applications will be slow to proliferate to potential adversaries due to high cost and technical complexity. However, LEL (i.e., d10kW average power) will be developed as technological byproducts of HEL and commercial applications, and will rapidly proliferate due to lost cost and reduced technical complexity. The U.S. Air Force, other military services, and other government agencies will field a wide variety of unmanned aerial vehicles by 2030. Most will be equipped with focal plane array (FPA)-based optical sensors in the ultra-violet, visible, and infra-red spectrum. FPAs are sensitive detectors constructed from dense arrays of very-large scale integrated circuit (VLSI) gates. As such, LELs pose a denial and degradation threat to these sensors.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Filtered Rayleigh Scattering Measurements in a Buoyant Flow Field
Filtered Rayleigh Scattering (FRS) is a non-intrusive, laser-based flow characterization technique that consists of a narrow linewidth laser, a molecular absorption filter, and a high resolution camera behind the filter to record images. Gases of different species have different molecular scattering cross-sections that become apparent as they pass through the interrogating laser light source, and this difference is used to discriminate between the different gaseous components. This study focuses on the behavior of a buoyant helium jet exiting horizontally into ambient air, and more specifically this jet's tendency to form side lobes that are discharged from the core fluid under low flow rate conditions. This jet behavior is documented and examined with relation to Froude, Grashof, and Reynolds numbers, and the behavior patterns are noted.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Shack-Hartmann and Interferometric Hybrid Wavefront Sensor
This document reports results of wave-optics simulations used to test the performance of a hybrid wavefront sensor designed to combine the self-referencing interferometer and Shack-Hartmann wavefront sensors in an optimal way. Optimal hybrid-wavefront sensor design required a thorough analysis of the noise characteristics of each wavefront sensor to produce noise models that assist in the design of an optimal phase-estimation algorithm. Feasible architectures and algorithms for combining wavefront sensors were chosen, and the noise models of the individual wavefront sensors were combined to form a model for the noise-induced error of the resulting hybrid sensor. The hybrid wavefront sensor and phase-estimation algorithm developed through this work showed improvement over a comparable stand-alone selfreferencing interferometer and Shack-Hartmann wavefront sensor in open-loop wave-optics simulations.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Quantum Mechanics: Volume 3
The universe we live in is both strange and interesting. This strangeness comes about because, at the most fundamental level, the universe is governed by the laws of quantum mechanics. This is the most spectacularly accurate and powerful theory ever devised, one that has given us insights into many aspects of the world, from the structure of matter to the meaning of information. This textbook provides a comprehensive account of all things quantum. It starts by introducing the wavefunction and its interpretation as an ephemeral wave of complex probability, before delving into the mathematical formalism of quantum mechanics and exploring its diverse applications, from atomic physics and scattering, to quantum computing. Designed to be accessible, this volume is suitable for both students and researchers, beginning with the basics before progressing to more advanced topics.

Electromagnetism
The author shows how, of the four forces of physical nature, it is the electromagnetic force that activates all of the nature around us as well as our bodies and brains. This force has been drawn upon throughout our entire evolution and plays an indispensable role in virtually all of modern technology.This book conveys the wonder of how this one force can do so much by describing how deeply embedded and intimately linked we are to earthly nature. Thus o竅ffering a refreshingly rich and encompassing perspective of our world by providing us with a deeper dimension in our reflections about our role as part of a cohesive whole.The electromagnetic workings of some of the core devices of modern technology, such as the transistor and laser are explained, along with the potential role that electromagnetism can play in our growing dependence on technology for our future evolution. Discussions on the various facets of electromagnetism are enriched by relating a number of engaging vignettes about its discoverers as well as anecdotes drawn from the author's own experience.

Connecting Physics Education Research and Practice
This book presents a selection of the most recent research results from the Italian physics education research community, aimed at enhancing the teaching and learning of physics. The motivation for this publication arises from the lack of a comprehensive reference for teachers on research results in physics education. Despite various physics curriculum reform initiatives, such as the introduction of modern physics into high school curricula, their effectiveness in improving the quality of physics teaching in schools has been limited. The book offers a contextualized view of the main topics in physics education, along with a comprehensive overview of the current challenges faced by physics education in Italy and abroad. It also presents research findings that could potentially enhance students' learning of physics. Throughout the book, the implications of these studies are outlined, acknowledging issues and knowledge gaps that will guide future research in physics education. Specifically, rather than covering all the contents addressed in the physics curriculum, the book presents research contributions that suggest potentially effective strategies, methods, and practices at different school levels, from primary school to secondary school and university level. Regarding physics content, the book presents teaching proposals highlighting conceptual aspects and exemplary methodologies of interpretation in physics, such as the physics of fluids and quantum mechanics. It also includes research contributions on different methods and proposals for implementing practical activities, reflecting on the role of the laboratory in learning the discipline and providing examples of integrating experimental and cognitive skills. The book also addresses the role of affective variables, such as physics identity, self-efficacy, and attitudes toward physics in the learning process. Additionally, studies on teachers' professional development are presented, which can inform the design of proposals for educational paths and methods, within a framework of close collaboration between schools and physics departments.

MIT computer scientist Rizwan Virk draws from research and concepts from computer science, artificial intelligence, video games, quantum physics, and ancient mystics to explain why we may be living inside a simulated reality like the Matrix. Simulation theory explains some of the biggest mysteries of quantum and relativistic physics, such as quantum indeterminacy, parallel universes, and the integral nature of the speed of light, using information and computation. Virk shows how the evolution of our video games, including virtual reality, augmented reality, artificial intelligence, and quantum computing, will lead us to a technological singularity. We will reach the simulation point, where we can develop all-encompassing virtual worlds like the OASIS in Ready Player One or The Matrix--and in fact we are already likely inside such a simulation. While the idea sounds like science fiction, many scientists, engineers, and professors have given the simulation hypothesis serious consideration, including Elon Musk, Neil deGrasse Tyson, and Nick Bostrom. But the simulation hypothesis is not just a modern idea. Philosophers of all traditions have long contended that we are living in some kind of "illusion" and that there are other realities that we can access with our minds. The Simulation Hypothesis is the definitive book on simulation theory and is now completely updated to reflect the latest developments in artificial intelligence and virtual reality. Whether you are a computer scientist, a fan of science fiction like the Matrix movies, a video game enthusiast, a spiritual seeker, or simply a fan of mind-bending thought experiments, you will never look at the world the same way again.

Back-Envelope Quant Mech (2nd Ed)
Dimensional and order-of-magnitude estimates are practiced by almost everybody but taught almost nowhere. When physics students engage in their first theoretical research project, they soon learn that exactly solvable problems belong only to textbooks, that numerical models are long and resource consuming, and that 'something else' is needed to quickly gain insight into the system they are going to study. Qualitative methods are this 'something else', but typically, students have never heard of them before.The aim of this book is to teach the craft of qualitative analysis using a set of problems, some with solutions and some without, in advanced undergraduate and beginning graduate Quantum Mechanics. Examples include a dimensional analysis solution for the spectrum of a quartic oscillator, simple WKB formulas for the matrix elements of a coordinate in a gravitational well, and a three-line-long estimate for the ionization energy of atoms uniformly valid across the whole periodic table. The pi癡ce de r矇sistance in the collection is a series of dimensional analysis questions in Integrable Nonlinear Partial Differential Equations with no dimensions existing a priori. Solved problems include the relationship between the size and the speed of solitons of the Korteweg-de Vries equation and an expression for the oscillation period of a Nonlinear Schr繹dinger breather as a function of its width.A new theme that appears in the second edition are the rare and exotic methods in elementary quantum mechanics. The new chapter covers quantum-mechanical supersymmetry, power index method, scale invariance, self-similarity, and circle inversion.

Nonlinear Optical Materials for All-Optical Switching Applications
This book highlights the background and fundamentals of nonlinear optical materials in relation to all-optical switching applications. It explains major aspects of nonlinear refractive index and the nonlinear absorption phenomena which are essential to decide the figure-of-merit of various materials for the all-optical switching. Autocorrelation technique, frequency-resolved optical gating, spectral phase interferometry for direct electric-field reconstruction, grating-eliminated no-nonsense observation of ultrafast incident laser light e-fields are discussed to measure the temporal and spectral profiles of the ultrafast pulsed lasers. Advanced nonlinear optical characterization methods such as single- and dual-arm Z-scan, pump-probe and beam deflection techniques are also discussed at length. The transmission signal obtained in the majority of the nonlinear optical effects is found to be weak which creates hiccups to obtain faster switching speeds. Various solutions are discussed to overcome these existing limitations of the all-optical switching-based devices. Optical nonlinearities in semiconductors, organic molecules and challenges in all-optical switching devices are also addressed in the book.
