The evaluation of electromagnetic field coupling to transmission lines is an important problem in electromagnetic compatibility. Traditionally, use is made of the TL approximation which applies to uniform transmission lines with electrically small cross-sectional dimensions, where the dominant mode of propagation is TEM. Antenna-mode currents and higher-order modes appearing at higher frequencies are neglected in TL theory. The use of the TL approximation has permitted to solve a large range of problems (e.g. lightning and EMP interaction with power lines). However, the continual increase in operating frequency of products and higher frequency sources of disturbances (such as UWB systems) makes that the TL basic assumptions are no longer acceptable for a certain number of applications. In the last decade or so, the generalization of classical TL theory to take into account high frequency effects has emerged as an important topic of study in electromagnetic compatibility. This effort resulted in the elaboration of the so-called 'generlized' or 'full-wave' TL theory, which incorporates high frequency radiation effects, while keeping the relative simplicity of TL equations. This book is organized in two main parts. Part I presents consolidated knowledge of classical transmission line theory and different field-to-transmission line coupling models. Part II presents different approaches developed to generalize TL Theory.

This special issue of Space Science Reviews contains selected papers on electromagnetic man-made and natural environmental interactions. Originally these papers were pre sented at the Fifth International Wrocfaw Symposium on Electromagnetic Compatibility. Wroclaw (Poland), 17-19 September, 1980, a biennial gathering of scientists and engineers. At that time, the symposium organizers selected a few persons of recognized authority and invited them to organize special sessions. Session organizers were given a free hand in the choice of topics and speakers. As a result, several impressive papers originated and a number of interesting people came to Wroclaw to discuss the recent results of their research. Professor Hiroshi Kikuchi from the Nihon University (J apan) was among them, serving as one of the most effective invited session chairmen/organizers at the symposium. The papers presented here were read at Prof. Kikuchi's session. At the symposium they received considerable attention not only because of the fascinating personalities and temperaments of the authors, but mainly because of the timeliness and soundness of their content. Their topic links both scientific and engineering fields in making attempts to resolve these kinds of specific hybrid problems. The problems discussed appear to be of interest not only to the EMC* community but also to a broader forum of persons interested in the areas of electrical and space science, and engineering in general. This opinion was confirmed during the URSI** symposium in Washington, D. C.

In chapters culled from the popular and critically acclaimed Electromagnetic Compatibility Handbook, Transmission Lines, Matching, and Crosstalk provides a tightly focused, convenient, and affordable reference for those interested primarily in this subset of topics. Author Kenneth L. Kaiser demystifies transmission lines, matching, and crosstalk and explains the source and limitations of the approximations, guidelines, models, and rules-of-thumb used in this field. The material is presented in a unique question-and-answer format that gets straight to the heart of each topic. The book includes numerous examples and uses Mathcad to generate all of the figures and many solutions to equations. In many cases, the entire Mathcad program is provided.

This book covers the principles of operation of electromagnetic waveguides and transmission lines. The approach is divided between mathematical descriptions of basic behaviors and treatment of specific types of waveguide structures. Classical (distributed-network) transmission lines, their basic properties, their connection to lumped-element networks, and the distortion of pulses are discussed followed by a full field analysis of waveguide modes. Modes of specific kinds of waveguides - traditional hollow metallic waveguides, dielectric (including optical) waveguides, etc. are discussed. Problems of excitation and scattering of waveguide modes are addressed, followed by discussion of real systems and performance.

Describes and illustrates various modeling techniques which are applicable to the area of EMC and includes material previously available only in international reports or other hard-to-obtain references. Electromagnetic topology, lumped-parameter circuit models, the radiation process, scalar diffraction theory for apertures, transmission line modeling, and models for shielding are among the topics discussed. The accompanying disk contains four programs based on the models developed in the text and can be used to calculate diverse transmission line responses.

INTRODUCTION TO ELECTROMAGNETIC COMPATIBILITY The revised new edition of the classic textbook is an essential resource for anyone working with today’s advancements in both digital and analog devices, communications systems, as well as power/energy generation and distribution. Introduction to Electromagnetic Compatibility provides thorough coverage of the techniques and methodologies used to design and analyze electronic systems that function acceptably in their electromagnetic environment. Assuming no prior familiarity with electromagnetic compatibility, this user-friendly textbook first explains fundamental EMC concepts and technologies before moving on to more advanced topics in EMC system design. This third edition reflects the results of an extensive detailed review of the entire second edition, embracing and maintaining the content that has “stood the test of time”, such as from the theory of electromagnetic phenomena and associated mathematics, to the practical background information on U.S. and international regulatory requirements. In addition to converting Dr. Paul’s original SPICE exercises to contemporary utilization of LTSPICE, there is new chapter material on antenna modeling and simulation. This edition will continue to provide invaluable information on computer modeling for EMC, circuit board and system-level EMC design, EMC test practices, EMC measurement procedures and equipment, and more such as: Features fully-worked examples, topic reviews, self-assessment questions, end-of-chapter exercises, and numerous high-quality images and illustrations Contains useful appendices of phasor analysis methods, electromagnetic field equations and waves. The ideal textbook for university courses on EMC, Introduction to Electromagnetic Compatibility, Third Edition is also an invaluable reference for practicing electrical engineers dealing with interference issues or those wanting to learn more about electromagnetic compatibility to become better product designers.
