Single mode equivalent network representations have been a key tool for the industrial design and development of a large variety of microwave systems. The reduced dimensions and increased complexity of modern microwave equipment, however, makes the inclusion of the higher order mode interactions essential for the correct industrial design and optimization of all microwave hardware. In this context, the analytical techniques originally exploited to develop single mode networks have recently been extended to produce multi-mode algorithms that can form the basis of fast and accurate Computer Aided Design tools. Furthermore, alternative multi-modal techniques, involving resonant rather than guided modes, have recently been developed for the design of waveguide components of arbitrary shape. This book describes in detail a number of modern multi-modal techniques for the analysis and design of passive microwave components. The authors comprehensively cover modal analysis of waveguides and cavities; discuss several multi-mode procedures for the study of both basic and arbitrarily shaped waveguide junctions and, finally, describe specific applications such as inductively coupled filters, waveguide couplers, metal insert and dual-mode filters. The book will be of interest to professional engineers and researchers in the microwave engineering field as well as students engaged in research at an advanced level. Distinctive features of this book include:
The technique of elastic scattering of electromagnetic radiation has been used as a diagnostic tool in various disciplines of science,engineering,medicine and agriculture.The investigations relating to above problems may be divided in three categories:(i)Scattering by a single particle,(ii)Scattering by a tenuous system of uncorrelated scatterers and (iii)Scattering by a concentrated dispersion of scatterers.In the proposed book,the primary effort is to examine the analytic solutions of the scattering problems of types (i) and (ii) in diverse backgrounds.For the completeness of the book,analytic solutions in scattering situations of type (iii) are also covered in reasonable details.

The main thrust of the rapid advance of microwave technology over the past four decades has been directed toward and powered by the development of new solid-state devices and circuits. In many cases, however, technological development has advanced with such speed that it has laxed the ability of professionals and educators to keep up with it, leaving both students and working electrical engineers with an incomplete knowledge of modern microwave technologies. Microwave Solid-State Circuits and Applications offers a comprehensive presentation of microwave technologies based on solid-state devices and circuits, with emphasis on operational principles and techniques for incorporating these devices into circuit applications. Fundamental design equations are derived and practical examples are given whenever possible. More than 300 illustrations serve to clarify principles and concepts under discussion, and a set of problems at the end of each chapter helps strengthen students' grasp of the subject. The book is organized into three sections: a review of fundamental principles in transmission lines and circuits, and semiconductor physics; two-terminal solid-state devices, circuits, and applications; and three-terminal solid-state devices, circuits, and applications. In addition, there is a special chapter on noise figures and some system parameters for receiver design. An ideal textbook for one-semester, senior-level or graduate courses in microwave solid-state circuits, this self-contained volume is also an excellent reference for practicing microwave, antenna, and solid-state engineers.
This extremely well organized introduction focuses on the special interactions that occur between circuits and devices. Understanding these interactions leads to an understanding of design and performance characteristics of solid-state microwave amplifiers and oscillators. The text is presented in three roughly equal sections, with each of the first two sections laying the groundwork for the third. The first five chapters present a detailed exposition of microwave circuits, their parameters, and how they are characterized. Topics discussed include transmission lines, waveguides, microstrip lines, Smith Chart analysis, linear network parameters, resonator-transmission line coupling and filters, and more. The discussion of solid-state devices, which constitutes the second part of the book, begins with sufficient theory to understand the operating principles of the devices discussed, including: Schottky barrier diodes, microwave transistors, varactor diodes, IMPATT diodes, and Gunn diodes. The final part of the book concerns the large signal effects produced in amplifiers and oscillators when solid-state devices are embedded in microwave circuits. Extended discussions include: transistor amplifier properties; the behavior of two-terminal negative resistance amplifiers with amplitude dependent negative resistance and susceptance; stability and locking characteristics of oscillators; and fundamental noise properties of amplifiers and the phase and amplitude noise of oscillators. With its dual emphasis on linear and nonlinear characteristics and a large number of completely worked-out examples, Microwave Devices, Circuits and Their Interaction is perfectly suited as a textbook for senior orfirst-year graduate courses. It is also a valuable tool for practicing engineers and scientists who wish to increase their understanding of microwave systems.
