    Book SynopsisFawwaz UlabySince joining the University of Michigan faculty in 1984, Professor Ulaby has directed numerous interdisciplinary projects aimed at the development of high-resolution satellite radar sensors for mapping Earth's terrestrial environment. He also served as the founding director of the NASA-funded Center for Space Terahertz Technology, whose research was aimed at the development of microelectronic devices and circuits that operate at wavelengths between the infrared and the microwave regions of the electromagnetic spectrum. He then served a seven-year term as the University of Michigan's vice president for research from1999-2005. Over his academic career, he has published 10 books and supervised more than 100 graduate students. Professor Ulaby is a member of the U.S. National Academy of Engineering, Fellow of the American Association for the Advancement of Science (AAAS) and the Institute of Electrical and Electronic Engineers (IEEE), and serves on several international scientific boards and commissions. In recognition for his outstanding teaching and distinguished scholarship, he has been the recipient of numerous honors and awards from universities, government agencies, and scientific organizations. Among them are the NASA Achievement Award (1990), the IEEE Millennium Medal(2000), the 2002 William Pecora Award, a joint recognition by NASA and the Department of the Interior, and the Distinguished FEA Alumni Award from the American University of Beirut (2006). In 2006, he was selected by the students in the Department of Electrical Engineering and Computer Science as Professor of the Year, and shortly thereafter, he was awarded the Thomas Edison Medal, the oldest medal in the field of electrical and computer engineering in the United States. Umberto RavaioliProfessor Ravaioli attended the University of Bologna, Italy, where he obtained degrees in Electronics Engineering and Physics. He conducted his dissertation work on fiber optics and microwaves at the laboratories of the Marconi Foundation in Villa Griffone, the summer estate where Guglielmo Marconi performed his first radio experiments. After developing interests in high-speed semiconductor devices and large-scale computation, he pursued a Ph.D. in Electrical Engineering at Arizona State University, where he developed Monte Carlo particle simulations for the high electron mobility transistor. He joined the Department of Electrical and Computer Engineering of the University of Illinois at Urbana-Champaign in 1986. He was a co-founder of the National Center for Computational Electronics, which promoted for over a decade the development of large-scale device simulation by leveraging resources at national supercomputing centers. His research group has developed Monte Carlo and quantum simulators for a wide range of semiconductor device applications, expanding recent activities to charge transport in biological systems, coupled electro-thermal simulation, and nanoelectronics. He is now the leader of the Computational Multiscale Nano-systems group at the Beckman Institute of the University of Illinois and is also serving as Senior Assistant Dean for Undergraduate Programs in the College of Engineering. Professor Ravaioli is a Fellow of the Institute of Electrical and Electronic Engineers (IEEE) and a Fellow of the Institute of Physics (IOP). He received the First Place Outstanding Paper Award at the 2007 IEEE International Conference on Electron Information Technology for his recent work on electro-thermal simulation.Table of Contents Introduction: Waves and Phasors Transmission Lines Vector Analysis Electrostatics Magnetostatics Maxwell's Equations for Time-Varying Fields Plane-Wave Propagation Wave Reflection and Transmission Radiation and Antennas Satellite Communication Systems and RadarSensors Appendix A Symbols, Quantities, and Units Appendix B Material Constants of Some Common Materials Appendix C Mathematical Formulas Appendix D Answers to Selected Problems

    Book SynopsisElectromagnetic compatibility (EMC) issues need to be an initial consideration in design and deployment of electronic transmitters or receivers, or in deployed systems containing both. This book provides methodologies for defining EMC requirements for the device, platform, site, and arena levels and techniques for performing predictions and calculations to achieve electromagnetic compatibility. While the book considers all transmitting and receiving systems and devices, it emphasizes military applications. Examples of the occurrence of electromagnetic problems are interference when devices are physically close and operating at the same, or similar, frequencies. In order to address this, the authors discuss several new approaches in mathematical development, such as the calculation of probability of interference based on frequency difference between two devices and the interference probability due to pulse to pulse interference. In theory, all the devices' parameters should be available for analysis, but in practice, missing data is not uncommon. The book aims to define default values that allow the performance of EMC analysis in cases where the data is missing, such as antenna patterns, intercardinal antenna gain and near field approximations. The treatment of EMC problems is quite mathematical and technical, but some chapters are intended for operational personnel such as system analysts, project managers and operations researchers.Trade ReviewAn excellent new reference is a recommended pick for college-level collections strong in electrical engineering and antenna design, offering engineers solid discussions of theory, applications, and different systems and their management. Uri Vered's Intersystem EMC Analysis, Interference, and Solutions considers new tools and methods for EMC requirements and techniques, including calculations, discussions of radar and communications systems, interference sources, and intersystem EMC. Techniques for performing EMC prediction and calculations key to problem-solving are essential to this book, which offers engineers step-by-step insights into EMC challenges and how they may be addressed. * Midwest Book Review *Table of ContentsDefinitions; EMC Requirements; EMC Analysis and Survey; Interference Type; Interference from Both Transmitter and Receiver; Interference from the Transmitter; Interference from the Receiver; Calculating the Received Interference Level; Interference Margin and Its Meaning; The Interference Range and the Reception Range; Propagation Models for EMC; Coupling Between Antennas; Relative Angels Between Antennas; Antenna Gain in Intercardinal Angles; Near Field; Interference Probability; Interference Probability-Antenna Patterns Aspect; Probability of Frequency Difference; Probability of Pulse Interference; Pulse Interference to Digital Communication; EMC Between Synchronous Hopping Devices; EMC Solutions; EMC Tests; Appendix-Device EMC Specifications Table.

    Book SynopsisDo you want to design a wireless transmitter or receiver for hand-held telephones? Have you wondered why the printed circuit wires on high-frequency circuits don''t always run in a straight line? This valuable text will answer all of your questions regarding component parasitics and circuit characterization for rf/microwave amplifier, oscillator, and filter circuit design and analysis. You will understand why capacitors act as inductors and vice versa and why amplifiers work like oscillators, while oscillators for local area networks work more like local area heaters.

    Book SynopsisAs the number of electrical devices in use continues to grow, so do the challenges of ensuring the electromagnetic compatibility (EMC) of products and systems. Fortunately, engineers have at their disposal an array of approximations, models, and rules-of-thumb to help them meet those challenges. Unfortunately, the number of these tools and guidelines is overwhelming, and worse still is the thought of investigating their origins and confirming their results.The Electromagnetic Compatibility Handbook is an unprecedented compilation of the many approximations, guidelines, models, and rules-of-thumb used in EMC analyses, complete with their sources and their limitations. The book presents these in an efficient question-and-answer format and incorporates an extremely comprehensive set of tables and figures. The author has either derived from basic principles or obtained and verified from their original sources all of the expressions in the tables. Mathcad was used to generate most Trade Review"Upon first glance of this book, my jaw dropped open and I stood there flipping from page to page. I cannot overstate the vast amount of knowledge this book contains. Each subject is covered from a basic point to a most advanced look. Huge equations cover the pages, yet more elementary concepts are explained in the simplest ways. But if you are like me, be forewarned! Opening this book you may find yourself flipping from page to page, concept to concept, and the original issue you wanted to research is long forgotten. …"Anyone who is seriously working in the EMC and ESD fields will need to consider seeing this book. I expect it should become a standard reference book for electromagnetic compatibility design and testing, as well as covering electrostatic discharge issues. It is both complex and advanced, but with enough basic materials to be useful to a more novice engineer or technician. As for me, I have gladly cleared a space on my desk, front and center, where this book will now remain within arm's reach." - IEEE EMC Society Newsletter, No. 2304, Winter 2004 "This book contains a vast range of material and is very thorough…well written and useful…One of the more striking aspects of the book is the large number of tables…I would like to emphasize that I find this book very useful. It is obvious that Prof. Kaiser has put a tremendous amount of effort, care, and consideration into this text. Also, given the amount of useful material in this book, it is definitely a bargain." - IEEE Microwave Magazine, Vol. 6, No. 2, June 2005"The book is useful for all the designers of electronic equipments: electrical and electronics engineers, technicians, professors, teachers. The content covers much more than EMC. The title should be 'All you should know to really master EMC'. It is an Encyclopaedia of Radio Engineering. …The presentation is compact, useful in all applications, with many figures, tables and graphics.... Including basics but also discussions and derivations never published before in book form guarantees that the book will be useful for many years ahead, even for these fast-evolution domains, as electronics and aerospace technology. -- Serban Birca-Galateanu,, Electrical and Electronic Engineering Dep., Nantes, Franc, for IEEE Power Electronics Society Newsletter, Volume 18, Number 3Table of ContentsEMI Sources.

    Book SynopsisThis textbook is an introduction to microwave engineering. The scope of this book extends from topics for a first course in electrical engineering, in which impedances are analyzed using complex numbers, through the introduction of transmission lines that are analyzed using the Smith Chart, and on to graduate level subjects, such as equivalent circuits for obstacles in hollow waveguides, analyzed using Green's Functions. This book is a virtual encyclopedia of circuit design methods. Despite the complexity, topics are presented in a conversational manner for ease of comprehension. The book is not only an excellent text at the undergraduate and graduate levels, but is as well a detailed reference for the practicing engineer.
