Publisher's Synopsis
Excerpt from Antennas: Theory and Practice
This book is about antennas: about the physical principles under lying their behavior, the theory needed in sound antenna design and in planning meaningful experiments, the applications of theory to antennas in various frequency ranges. We have written it primarily for students and practitioners of radio engineering. But no specialized engineering background is required for understanding it, and the book should be intelligible to students of applied mathematics and physics and to mathematical consultants in industry. For them this book will illus trate the type of problems of interest to radio engineers, the nature of solutions sought by them, the ways in which applicable mathematics is actually put to work by practical men.
The contents of this book express our idea Of what a college text book On antennas should contain. It is not a book of descriptive type, nor is it concerned with engineering details. Such details are learned best on the job, and college time should not be consumed by studying books that can be read at any time, and with profit, without the instruo tor's assistance. But a serious study Of fundamental ideas and theory re quires time and often the help that only college can provide. Good understanding of fundamental theory will enable the student to acquire confidence in himself, and will develop his ability to evaluate what he finds in technical periodicals. Thus he will be prepared to make full and appropriate use of available information. To make the book more usable as a reference book, an extensive index and a list of symbols have been added.
We have not evaded derivations of important formulas and proofs Of important conclusions. The student should know them. He has a right to know them. But we have made a serious effort to make them as simple as possible. Anyone who has a working knowledge of general physics and calculus is adequately prepared for this book provided he possesses scientific courage. He should not be intimidated by a partial differential equation simply because he has never had a course in such equations. We do not use vector analysis because in the type of prob lems with which we are concerned it impedes rather than promotes understanding. We use the vector concept and, in a very few cases, shorthand notations for scalar and vector products; but these notations are normally acquired in studying physics and do not really constitute vector analysis.
