Book Description
Topics in Millimeter Wave Technology, Volume 1 presents topics related to millimeter wave technology, including fin-lines and passive components realized in fin-lines, suspended striplines, suspended substrate microstrips, and modal power exchange in multimode fibers. A miniaturized monopulse assembly constructed in planar waveguide with multimode scalar horn feeds is also described. This volume is comprised of five chapters; the first of which deals with the analysis and synthesis techniques for fin-lines as well as the various passive components realized in fin-line. Tapers, discontinuities, directional couplers, filters, and non-reciprocal devices are considered, along with attenuators, switches, detectors, phase modulators, mixers, and oscillators. The second chapter focuses on millimeter-wave planar integrated circuit filters, with particular reference to lowpass filter design that forms the basis for the bandpass filter design. The third chapter describes H-plane millimeter-wave planar transmission lines and circuits, along with various passive and active components realized using suspended substrate microstrips. The fourth chapter examines modal power dynamics and transmission characteristics of multimode optical fibers. The relation between a ray theory and a wave theory is also explained, and a theory of mode coupling and the modal power exchange is discussed. The book concludes with a chapter on planar waveguide versions of the classic dual-plane, amplitude-monopulse comparator realized in conjunction with a unique multimode scalar feed horn. This book will be of interest to students and practitioners of electronics and electrical engineering.

Book Description
Innovations in Telecommunications, Part A contains the proceedings of the symposium on "Innovations in Telecommunications" of the International Symposium Series held in Kuwait in April 1981 and sponsored by the Kuwait Foundation for the Advancement of Science. The symposium provided a forum for reviewing advances in research, development, demonstration, design, manufacture, field testing, and application in the field of telecommunications. Both the state of the art and the cutting edge of technology in telecommunications are given emphasis. Comprised of 17 chapters, this book is arranged in five major sections: signal processing; devices and microfabrication techniques; terrestrial communications; satellite communication; and applications. The discussion begins with an assessment of trends in electronic information transfer, followed by a description of a bandwidth- and power-efficient modulation system that combines convolutional encoding and phase modulation. Subsequent chapters deal with voice processing techniques; image processing for communication; developments in switching; and devices such as those for transmission and delta modulation. The final section is devoted to terrestrial communications and covers microwave systems, mobile and lightwave communications, and coaxial cable systems for land and sea. This monograph will be of interest to those in the telecommunications industry.

Book Description
The Wave Concept Iterative Procedure (WCIP) method has found an increasing number of users within electromagnetic theory and applications to planar circuits, antennas and diffraction problems. This book introduces in detail this new formulation of integral methods, based on the use of a wave concept with two bounded operators, and applications in a variety of domains in electromagnetics. This approach presents a number of benefits over other integral methods, including overcoming the problem of singularity, and reduced computing time. Through the presentation of mathematical equations to characterize studied structures and explanation of the curves obtained, via validated examples, the authors provide a thorough background to electromagnetism as well as a professional reference to students and researchers.

Book Description
The development of equipment capable of producing and monitoring safe, effective and predictable hyperthermia treatments represents a major challenge. The main problem associated with any heating technique is the need to adjust and control the distribution of absorbed power in the tissue during treatment. Power distribution is considered adequate only when tumor tissue can be maintained at the required hyperthermic levels while, at the same time, healthy tissue is not overheated. This problem is particularly crucial when external heating devices are used to produce hyperthermia. Ex ternal hyperthermia refers to those methods which supply heat to tumor tissue in an external, noninvasive manner, as opposed to internal hyperther mia by which heat is supplied to tumor tissue in situ. Until recently, most of the technical developments and clinical trials of ther motherapy for superficial and deep tumors have been based on elec tromagnetic systems. Presently, there is increasing interest in the use of ultra sound to accomplish these goals. Electromagnetic techniques of external thermotherapy include radiative, capacitive, and, to a lesser extent, inductive procedures. Recent designs for radiative applicators have incorporated microstrip structures. These have the advantage of being compact and lightweight compared with dielectrically loaded waveguide applicators.
