Book Synopsis Frequency Selective Surfaces by : Ben A. Munk
Download or read book Frequency Selective Surfaces written by Ben A. Munk and published by John Wiley & Sons. This book was released on 2005-03-11 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: "...Ben has been the world-wide guru of this technology, providing support to applications of all types. His genius lies in handling the extremely complex mathematics, while at the same time seeing the practical matters involved in applying the results. As this book clearly shows, Ben is able to relate to novices interested in using frequency selective surfaces and to explain technical details in an understandable way, liberally spiced with his special brand of humor... Ben Munk has written a book that represents the epitome of practical understanding of Frequency Selective Surfaces. He deserves all honors that might befall him for this achievement." -William F. Bahret. Mr. W. Bahret was with the United States Air Force but is now retired. From the early 50s he sponsored numerous projects concerning Radar Cross Section of airborne platforms in particular antennas and absorbers. Under his leadership grew many of the concepts used extensively today, as for example the metallic radome. In fact, he is by many considered to be the father of stealth technology. "This book compiles under one cover most of Munk's research over the past three decades. It is woven with the physical insight that he has gained and further developed as his career has grown. Ben uses mathematics to whatever extent is needed, and only as needed. This material is written so that it should be useful to engineers with a background in electromagnetics. I strongly recommend this book to any engineer with any interest in phased arrays and/or frequency selective surfaces. The physical insight that may be gained from this book will enhance their ability to treat additional array problems of their own." -Leon Peters, Jr. Professor Leon Peters, Jr., was a professor at the Ohio State University but is now retired. From the early sixties he worked on, among many other things, RCS problems involving antennas and absorbers. This book presents the complete derivation of the Periodic Method of Moments, which enables the reader to calculate quickly and efficiently the transmission and reflection properties of multi-layered Frequency Selective Surfaces comprised of either wire and/or slot elements of arbitrary shape and located in a stratified medium. However, it also gives the reader the tools to analyze multi-layered FSS's leading to specific designs of the very important Hybrid Radome, which is characterized by constant band width with angle of incidence and polarization. Further, it investigates in great detail bandstop filters with large as well as narrow bandwidth (dichroic surfaces). It also discusses for the first time, lossy elements used in producing Circuit Analog absorbers. Finally, the last chapter deals with power breakdown of FSS's when exposed to pulsed signals with high peak power. The approach followed by most other presentations simply consists of expanding the fields around the FSS, matching the boundary conditions and writing a computer program. While this enables the user to obtain calculated results, it gives very little physical insight and no help in how to design actual multi-layered FSS's. In contrast, the approach used in this title analyzes all curves of desired shapes. In particular, it discusses in great detail how to produce radomes made of FSS's located in a stratified medium (Hybrid Radomes), with constant band width for all angles of incidence and polarizations. Numerous examples are given of great practical interest. More specifically, Chapter 7 deals with the theory and design of bandpass radomes with constant bandwidth and flat tops. Examples are given for mono-, bi- and tri-planar designs. Chapter 8 deals with bandstop filters with broad as well as narrow bandwidth. Chapter 9 deals with multi-layered FSS of lossy elements, namely the so-called Circuit Analog Absorbers, designed to yield outstanding absorption with more than a decade of bandwidth. Features material previously labeled as classified by the United States Air Force.
Download or read book Metamaterials written by Benedikt A. Munk and published by John Wiley & Sons. This book was released on 2009-02-17 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Convincing and Controversial Alternative Explanation of Metamaterials with a Negative Index of Refraction In a book that will generate both support and controversy, one of the world's foremost authorities on periodic structures addresses several of the current fashions in antenna design—most specifically, the popular subject of double negative metamaterials. Professor Munk provides a comprehensive theoretical electromagnetic investigation of the issues and concludes that many of the phenomena claimed by researchers may be impossible. While denying the existence of negative refraction, the author provides convincing alternative explanations for some of the experimental examples in the literature. Although the debate on this subject is just beginning, Professor Munk has received support by various numerical simulations, winning him the encouragement of numerous experts in the field. The issues that are raised here have not been addressed thoroughly by the metamaterials community, and this book will serve as a catalyst for much healthy debate and discussion. Metamaterials: Critique and Alternatives is destined to become a classic resource for graduate students and researchers in electromagnetics, antenna theory, materials research, and chemistry.
Book Synopsis Suppression of Surface Waves on Arrays of Finite Extent by : Jonothan B. Pryor
Download or read book Suppression of Surface Waves on Arrays of Finite Extent written by Jonothan B. Pryor and published by . This book was released on 2000 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A finite passive periodic antenna array, or Frequency Selective Surface, exhibits a phenomenon that an infinite passive array, or FSS, does not. Namely, surface waves which propagate along the periodic array structure may be induced in the array at frequencies below the resonant frequency of the array. These surface waves may radiate energy when they reach the ends or other discontinuities in the finite array and may therefore increase the Radar Cross Section of the array.

This book was released on 2007-06-20 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions to this volume deliberate the electrical and magnetic properties of materials relevant to the design of unconventional antennas, microwave circuits/components, anti-reflection media and coatings, EMI shielding structures, radomes, etc. Though a classical research topic, some recent advancements in technology have led to new capabilities to create and control fine-scale structures. This has inspired scientists to develop new materials with exceptionally high permittivity or permeability, as well as metamaterials (or negative index materials) with unusual electromagnetic properties. Novel materials based on the use of active devices to control their electromagnetic performance have also been proposed. The multi-disciplinary nature of these new materials has brought together researchers from materials science, physics and electrical engineering to explore and deepen our current understanding of electromagnetic wave propagation. A wide range of new commercial/defence applications of these materials is expected to emerge in the near future.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the developments and potential applications of Meta-Smith charts, which can be applied to practical and useful transmission line problems (e.g., metamaterial transmission lines and nonreciprocal transmission lines). These problems are beyond the capability of the standard Smith chart to be applied effectively. As any RF engineer is aware, a key property of the Smith chart is the insight it provides, even in very complex design processes. Like the Smith chart, Meta-Smith charts provide a useful way of visualizing transmission line phenomena. They provide useful physical insight, and they can also assist in solving related problems effectively. This book can be used as a companion guide in studying Microwave Engineering for senior undergraduate students as well as for graduate students. It is also recommended for researchers in the RF community, especially those working with periodic transmission line structures and metamaterial transmission lines. Problems are also provided at the end of each chapter for readers to gain a better understanding of material presented in this book.

This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the first ICASE/LaRC Work shop on Computational Electromagnetics and Its Applications conducted by the Institute for Computer Applications in Science and Engineering and NASA Langley Research Center. We had several goals in mind when we decided, jointly with the Elec tromagnetics Research Branch, to organize this workshop on Computa tional Electromagnetics ( CEM). Among our goals were a desire to obtain an overview of the current state of CEM, covering both algorithms and ap plications and their effect on NASA's activities in this area. In addition, we wanted to provide an attractive setting for computational scientists with expertise in other fields, especially computational fluid dynamics (CFD), to observe the algorithms and tools of CEM at work. Our expectation was that scientists from both fields would discover mutually beneficial inter connections and relationships. Another goal was to learn of progress in solution algorithms for electromagnetic optimization and design problems; such problems make extensive use of field solvers and computational effi ciency is at a premium. To achieve these goals we assembled the renowned group of speakers from academia and industry whose talks are contained in this volume. The papers are printed in the same order in which the talks were pre sented at the meeting. The first paper is an overview of work currently being performed in the Electromagnetic Research Branch at the Langley Research Center.

Book Synopsis Design and Testing of a Frequency Selective Surface (FSS) Based Wide-band Multiple Antenna System by : Dana C. Kohlgraf
Download or read book Design and Testing of a Frequency Selective Surface (FSS) Based Wide-band Multiple Antenna System written by Dana C. Kohlgraf and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Since the first radio link was built by Hertz in 1886, antennas have become a critical technology which allows people to stay connected and informed. Several advances have been made in the field of antenna theory and technology in the past hundred twenty years. Among them is the characterization of frequency selective surfaces (FSS), which are periodic arrays of passive elements or slots that act as a band stop or a band pass filters respectively to propagating electromagnetic waves. The purpose of this project was to construct an antenna which is transmissive outside of the band of operation. For example, the antenna designed in this project operates in a band of 1-2 GHz. The goal of this project is to be able to place an antenna operating at 4-8 GHz behind this antenna and have it be able to "look though" the first antenna as if it wasn't there. This will allow the user to stack antennas one behind the other and thus increase the density of antennas in a given area. This is advantageous in applications where the available real estate upon which to place antennas is limited, such as on ships and submarines. This antenna has two main components - an array of radiating elements and a reflector. The radiating array will be transmissive at 4-8 GHz as long as it does not radiate energy at this frequency and does not significantly scatter energy. These constraints are easily met by creating an array of wire elements. Reflectors, on the other hand, are commonly composed of a solid metal plate, which will reflect energy at any frequency. However, this project uses an element FSS for a reflector. As a result this reflector will only reflect energy in the stop band. Sufficiently outside of this band, it will be transmissive. While an entire antenna was designed for sake of completeness, the focus of this project was the design and testing of the FSS reflector. There were two main components to this project. The first was to use computational codes to design the antenna. Specifically, the antenna was designed using a Method of Moments (MoM) code, which calculates gain patterns for finite antennas. These results were then compared to a periodic moment method code, which calculates the ideal result for an infinite structure. This design process was completed in several steps. First the FSS array was designed to be reflective in the L band (1-2 GHz) and transmissive outside of this band. Following this the radiating array was designed to realize sufficiently flat L band bandwidth. The FSS reflector and radiating array were then combined together and the gain and transmissivity were then calculated for the entire antenna. Finally a prototype of the FSS reflector was built and tested. Time constraints prevented the construction of the entire antenna. The results of these tests are in very good agreement with each other. MoM tests show the FSS is within 1 dB of perfect reflectivity over the entire L band range. The prototype was within 2 dB of perfect reflectivity over the same range. This deviation is explained by unavoidable human error in the construction of the FSS. The periodic moment method code is also computed similar results. The bandwidth wasn't quite as large in the PMM test, but this is expected and is explained by the fact that edge diffraction on finite structures increases the bandwidth. The transmissivity of this FSS is within 2 dB of perfect transmissivity in the C band (4-8 GHz.) Finally the gain of the radiating array has a 2 dB variation over L and, and the gain of the entire antenna has a 3 dB variation over L band.
