Hardback. Condition: New. Radar Principles for the Non-specialist, 3rd Edition continues its popular tradition: to distil the very complex technology of radar into its fundamentals, tying them to the laws of nature on one end and to the most modern and complex systems on the other. It starts with electromagnetic propagation, describes a radar of the utmost simplicity, and derives the radar range equation from that simple radar. Once the radar range equation is available, the book attacks the meaning of each term in it, moving through antennas, detection and tracking, radar cross-sections, waveforms and signal processing, and systems applications. At the finish, the reader should be able to do an acceptable, first order radar design and to critique the design of others. Students, engineers, scientists and managers will benefit from this book. The more noticeable enhancements to the third edition are the additions of equation numbers, more numerical examples, tables and figures showing many of the concepts numerically, and exercises for almost all of the concepts. These enhancements make the book easier to learn from and easier to teach out of.

Hardback. Condition: New. Improvements in the accuracy, computational cost, and reliability of computational techniques for high-frequency electromagnetics (including antennas, microwave devices and radar scattering applications) can be achieved through the use of 'high-order' techniques. This book outlines these techniques by presenting high-order basis functions, explaining their use, and illustrating their performance. The specific basis functions under consideration were developed by the authors, and include scalar and vector functions for use with equations such as the vector Helmholtz equation and the electric field integral equation. The book starts by considering the approximation of scalar functions, and explores the error in some of those representations. Singular functions (those that are unbounded) are also considered, since these often arise in practical EM problems. The authors then discuss the approximation of vector functions, and summarize the various classes of vector basis functions that have been used by the professional community. Following this, they present higher-order basis functions for the most common cell shapes used in finite element analysis procedures. Finally, they consider some of the implementation details associated with the use of these functions for integral equation/method of moments formulations and differential equation/finite element method approaches. This book provides an essential introduction to these techniques for researchers, graduate students and practicing professionals in the discipline of computational electromagnetics.

Hardback. Condition: New. The objective of this book is to introduce students and interested researchers to antenna design and analysis using the popular commercial electromagnetic software FEKO. This book, being tutorial in nature, is primarily intended for students working in the field of antenna analysis and design; however the wealth of hands-on design examples presented in this book along with simulation details, makes it a valuable reference for practicing engineers. The requirement for the readers of this book is to be familiar with the basics of antenna theory; however electrical engineering students taking an introductory course in antenna engineering can also benefit from this book as a supplementary text. The key strengths of this book are as follows: First, the basics of antenna simulation will be presented in a detailed, understandable, and easy to follow procedure through study of the simplest types of radiators, i.e. dipole and loop antennas, in chapters 2 and 3. This will build the fundamental knowledge a student would need in order to utilize antenna simulation software in general. Second, comparison between theoretical analysis and full-wave simulation results of FEKO are given for a variety of antenna types, which will aid the readers with a better understanding of the theory, approximations and limitations in the theoretical analysis, and solution accuracy. Third, and of paramount importance, is the visualization of the antenna current distribution, radiation patterns, and other radiation characteristics that are made available through full-wave simulations using FEKO. A proper analysis of the radiation characteristics through these visualizations serves as a powerful educational tool to fully understand the radiation behaviour of antennas.

Hardback. Condition: New. The long awaited revision of the classic book Transmission Line Transformers, by Jerry Sevick, is now in its fifth edition and has been updated and reorganised by Raymond Mack to provide communication engineers with a clear technical presentation of both the theory and practical applications of the transmission of radio communication. Sevick's Transmission Line Transformers: Theory and Practice, 5th Edition reviews the underlying principles that promote a better understanding of transmission line transformers. Ideal for academics and practicing engineers, this edition is divided into two clear parts for easy reference. Part one is a review of the theory and new concepts, including a discussion on the magnetic properties that affect the core of a transmission line transformer. Part two essentially focuses on the 'practice' element of the book title. This section has been updated to reflect the significant changes in component suppliers over the 30 years since the first edition of the book. Highlights of this title include the coverage of substantial background theory, recent work on fractional ratio transformers and high power Balun designs, and provides updated sources for transformer materials to reflect mergers, sales, and business failures over the past 20 years. There is also expanded coverage of commercial sources of low impedance coaxial cable; expanded construction hints for purpose built rectangular parallel transmission lines; plus an updated test equipment chapter to reflect modern computer based experimenter grade test equipment sources. Ray has leveraged his experience with ferrite materials for switching power to explain the performance characteristics of the ferrite materials used for RF power transmission line transformers.

Hardback. Condition: New. This book begins with an essential background discussion of the many applications and drawbacks for paraxial beams, which is required in the treatment of the complex space theory of spatially localized electromagnetic waves. The author highlights that there is a need obtain exact full-wave solutions that reduce to the paraxial beams in the appropriate limit. Complex Space Source Theory of Spatially Localized Electromagnetic Waves treats the exact full-wave generalizations of all the basic types of paraxial beam solutions. These are developed by the use of Fourier and Bessel transform techniques and the complex space source theory of spatially localized electromagnetic waves is integrated as a branch of Fourier optics. Two major steps in the theory are described as: 1) the systematic derivation of the appropriate virtual source in the complex space that produces the required full wave from the paraxial beam solution and 2) the determination of the actual secondary source in the physical space that is equivalent to the virtual source in the complex space.

Hardback. Condition: New. Very simply, electromagnetic interference (EMI) costs money, reduces profits, and generally wreaks havoc for circuit designers in all industries. This book shows how the analytic tools of circuit theory can be used to simulate the coupling of interference into, and out of, any signal link in the system being reviewed. The technique is simple, systematic and accurate. It enables the design of any equipment to be tailored to meet EMC requirements.Every electronic system consists of a number of functional modules interconnected by signal links and power supply lines. Electromagnetic interference can be coupled into and out of every conductor. A review of the construction of the wiring assemblies and the functions of the signals they carry will allow critical links to be identified. Circuit modeling can be used to simulate the electromagnetic coupling mechanism of each critical link, allowing its performance to be analyzed and compared with the formal requirements. Bench testing during the development of any product will allow any interference problem to be identified and corrected, long before the manufactured unit is subjected to formal testing. Key Features: A fully outlined, systematic and dramatically simplified process of designing equipment to meet EMC requirements; Focuses on simplifications which enable electrical engineers to singularly handle EMC problems; Helps minimize time-to-market of new products and reduces the need for costly and time-consuming modifications; Outlines how general purpose test equipment (oscilloscopes and signal generators) can be used to validate and refine any model; Discusses how to use Mathcad or MATLAB® to perform analysis and assessment.

Hardback. Condition: New. A cognitive radio is a transceiver which is aware of its environment, its own technical capabilities and limitations, and those of the radios with which it may communicate; is capable of acting on that awareness and past experience to configure itself in a way that optimizes its performance; and is capable of learning from experience. In a real sense, a cognitive radio is an intelligent communications system that designs and redesigns itself in real time. Cognitive Radio Engineering is both a text and a reference book about cognitive radio architecture and implementation, intended for readers who want to design and build working cognitive radios. It takes the reader from conceptual block diagrams through the design and evaluation of illustrative prototypes. An important goal is to bridge the divide between radio engineers, who often have little experience with the computational resource and timing issues inherent in cognitive radios, and computer engineers who often are unaware of RF issues like dynamic range, intermodulation products, and acquisition time. Following a brief overview of cognitive radio history and a high-level look at cognitive radio operation, the book presents a detailed study of cognitive engine design and analysis. After treating RF subsystems the book considers computational platforms and computation issues in cognitive radios, followed by system integration, evaluation methods for cognitive radio, and cognitive radio design for networking. The book concludes with coverage of cognitive radio applications in communications.

Hardback. Condition: New. This handbook outlines the factors that must be considered in designing circuits, equipment, and systems for electromagnetic compatibility (EMC). It teaches circuit and system designers practical approaches to thwart the ever present culprit of electromagnetic interference (EMI). By emphasizing the fundamentals, it provides information that will help readers understand the rationale that forms the basis for many of the EMC practices and procedures. There is much information about these topics available in disparate forms (journal articles, symposia proceedings, etc.) but this book brings the critical knowledge into a single source for battling EMI. The goal of all device and system designs that must function in an electromagnetic environment (i.e. radio, TV, radar, navigation, and communications) is to operate without adversely affecting other electronic equipment or systems. The inverse is also true. The requirement for sharing spectrum has reached international levels of concern and it must be dealt with in proportion to the safety and economic impact involved. Designing Electronic Systems for EMC outlines how.
