Hardback. Zustand: 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. Zustand: 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. Zustand: 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. Zustand: 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.
