" ... This study concludes that high power microwave weapons systems offer the prospect of significant offensive and defensive capabilities for all of the military services. The principal recommendations include the suggestion that the Department of Defense and the Air Force establish a High Power Microwave Systems Program Office for the purpose of developing these weapons and integrating them into the combatant commands. This systems program office should be a joint program office that involves the participation of the Army, Navy, and Marine Corps as well as other agencies. Only then will the U.S. military be able to maximize the development of microwave applications, minimize costs, and facilitate the transition of this unique technology to the military services and other government agencies. Not only should defense contractors be encouraged to develop the technical capabilities that would permit them to participate in microwave weapons programs, but this study also concludes that all U.S. military system should be hardened to protect them against the effects of microwaves."--Page v

Download High Power Microwave Generation Using an Active Metamaterial Powered by an Electron Beam Book in PDF, ePub and Kindle
This thesis presents the theory, design, and experimental demonstration of coherent microwave generation at 2.4 GHz in a metamaterial loaded waveguide using a 490 keV, 84 A, one microsecond pulse length electron beam that produced more than 5 MW of microwave power. Three different metamaterial structure designs named MTM1, MTM2, and MTM3 were tested with design frequencies of 2.8, 2.4, and 3.7 GHz, respectively. The waveguides were loaded with two metamaterial plates that were machined with complementary split ring resonators with periods ranging from 5 to 10 mm. The metamaterial waveguides supported two distinct modes: a symmetric mode that occurs when the two metamaterial plates were excited in phase, and an antisymmetric mode that occurs when the metamaterial plates were excited out of phase. The electron beam propagated on axis between the metamaterial plates. The output radiation was studied for solenoid magnetic field values in the range 350 to 1600 G and for beam voltages from 350 to 500 kV. The best results were found in a 370 mm long structure using the MTM2 design, where output power levels of up to 5 MW were obtained at 400 G in the antisymmetric mode at a frequency near 2.39 GHz. The frequency tuning vs. magnetic field for operation at a power level exceeding 1 MW was consistent with that predicted by an anomalous Doppler shifted resonance condition, [omega] = [kappa]z[upsilon]z - [Omega]c/[gamma]. At magnetic fields above 750 G, the microwave output switched to the symmetric mode at a frequency near 2.44 GHz, but the power level dropped drastically to below 100 W. In contrast to the antisymmetric mode, the frequency tuning of the symmetric mode was consistent with that predicted by a normal Cherenkov resonance, [omega] = [kappa]z[upsilonl]z. CST PIC simulations predict the observed output frequencies and the switch between modes at 750 G. However, the CST simulations also predict multi-megawatt power levels in both modes, which was observed in the antisymmetric mode, but not the symmetric mode. The discrepancy between the symmetric mode output power of the simulations and experiment Is unexplained. To the authors knowledge, these are the first reported experimental results of high power (> 1 MW) microwave generation from an electron beam interacting with a metamaterial structure. The results are important for the development of new microwave sources and novel devices which utilize active metamaterials

Download Modern Radio Signals Filtering Devices Methods, Technologies, & Structures Book in PDF, ePub and Kindle
This comprehensive book covers spectral analysis theory for radio signals and innovative devices designed for filtering electromagnetic waves across diverse frequency ranges. The book features 14 chapters that explain the working of devices utilizing surface and bulk acoustic waves. The chapters provide insights into acousto-optical and acousto-electronic Fourier processors' design principles, description methods, and characteristics. The inclusion of algorithms for multi-channel frequency discriminators enhances the precision of radio signal frequency measurements, ensuring stability in tracking frequency meters amidst intense interference. The book also includes mathematical modeling and experimental studies of waveguide microwave filters and X-band multiplexers, specifically tailored for non-pressurized radio electronic equipment in space communication systems. Notably, the book introduces readers to a compelling alternative to conventional filters: 2-D periodic structures in the form of thin perforated metal meshes that offer compact solutions for millimeter and sub-millimeter wave systems. A significant portion of the book is dedicated to the development of highly selective microstrip filters, incorporating complex topological structures with limited resonators and numerous couplings. This approach allows for the formation of numerous attenuation poles at finite frequencies, facilitating the achievement of high electrical parameters and compact filter sizes. Engineers and scientists specializing in communication systems design and analog Fourier processors will find a wealth of well-established and original solutions within this book.

Download Electromagnetic Metamaterials Book in PDF, ePub and Kindle
Electromagnetic metamaterials-from fundamental physics to advanced engineering applications This book presents an original generalized transmission line approach associated with non-resonant structures that exhibit larger bandwidths, lower loss, and higher design flexibility. It is based on the novel concept of composite right/left-handed (CRLH) transmission line metamaterials (MMs), which has led to the development of novel guided-wave, radiated-wave, and refracted-wave devices and structures. The authors introduced this powerful new concept and are therefore able to offer readers deep insight into the fundamental physics needed to fully grasp the technology. Moreover, they provide a host of practical engineering applications. The book begins with an introductory chapter that places resonant type and transmission line metamaterials in historical perspective. The next six chapters give readers a solid foundation in the fundamentals and practical applications: Fundamentals of LH MMs describes the fundamental physics and exotic properties of left-handed metamaterials TL Theory of MMs establishes the foundations of CRLH structures in three progressive steps: ideal transmission line, LC network, and real distributed structure Two-Dimensional MMs develops both a transmission matrix method and a transmission line method to address the problem of finite-size 2D metamaterials excited by arbitrary sources Guided-Wave Applications and Radiated-Wave Applications present a number of groundbreaking applications developed by the authors The Future of MMs sets forth an expert view on future challenges and prospects This engineering approach to metamaterials paves the way for a new generation of microwave and photonic devices and structures. It is recommended for electrical engineers, as well as physicists and optical engineers, with an interest in practical negative refractive index structures and materials.

A workshop was convened from June 3-12, 1999 at the University of New Mexico's Maui High Performance Computing Center. The purpose of the workshop was to bring together contributors to an IEEE Press Book entitled Advances in High Power Microwave Sources and Technologies in order to draft the initial manuscript. Workshop participants discussed competing ideas and converged on an initial draft. The scientific papers presented at the workshop thus comprise the book draft. Goals were then made for finalizing the book, having assigned tasks to each of the contributors. There will be 12 chapters describing recent advances in AFOSR-funded high power microwave research. Each chapter is led by a Chapter Master whose task is to coordinate the contributions from the chapter coauthors. In addition to this aspect of the workshop, technical sessions discussing the role of high performance computing on high power microwave tube design were also held. There were 29 registered attendees at the workshop.
