Electromagnetics for communication engineering [Book Review]

74 September 2004 Electromagnetics for Communication Engineering Several things come to my mind when I see a new text on electromagnetics. First, I wonder why we need another text on electromagnetics. After all, Maxwell’s equations have not changed. Certainly books, such as those by Harrington, Collin, Jordan, and Balmain, as well as Ramo, Whinnery and Van Duzer have all done excellent jobs of covering electromagnetics. These old texts range between theoretical and practical and all have something to offer. Second, my wife, a computer science major, has said more than once that I should throw out these old texts because they are out of date. The fact is that Dr. Russer’s book on electromagnetics offers a fresh perspective on solving field problems. Electromagnetics, Microwave Circuit and Antenna Design for Communications Engineering is a complete, concise, and up-to-date treatment of electromagnetics for engineers. This book starts with fundamental principles and works its way through many applications of electromagnetics. The new twists for this text are an emphasis on differential forms and a chapter on numerical methods. Dr. Russer’s text is a comprehensive introduction to electromagnetics. The book is suitable for an engineering reference or as a text for a short course. Because the book has no problems, it is not designed for undergraduate teaching but could be used at the graduate level with supplementary problems. The references cited in this text are obviously selected with care. The strong points for this text are its thorough derivations and emphasis on boundary conditions and fundamentals. An entire chapter is devoted to surfaces, currents, and waves. Using differential forms for much of the electromagnetic development is different from the typical approach with gradients, divergences, and curls. For those more familiar with vector notation, the first appendix ties the two disciplines together. Also, the emphasis on boundary conditions and differential forms dovetails nicely with the chapter on numerical methods. This text has a decided
