This book is written by practicing engineers for practicing engineers and university students of all levels planning to incorporate electrodynamics into their professional toolbox. The text is illustrated by full-color images as well a set of computer simulation results and could be a practical introduction to the application of electromagnetics.
Over many years in the engineering field and teaching electrodynamics, the authors have observed that students and engineers are very results oriented and prefer to avoid extensive mathematical manipulations. And they are basically right because the present day the numerical modeling of electromagnetic problems by commercially available and user-friendly software alleviates much of the need for in-depth-mathematical-proficiency. Following this trend, we decided to minimize mathematics whenever possible and focused primarily on an intuitive grasp of the material through a deep understanding of physical analogies, unit dimension analysis, simplified models, etc. We developed this user-friendly book as selfcontained, reader-oriented, and easy-to-understandable by cutting each chapter into small portions of 3 - 5 pages. We hope that chunking helps the motivated readers identify key words and ideas, develops their ability to paraphrase, and makes it easier for them to organize and synthesize information, stimulates their self-study. The book can be useful as a text/supplement in standard university courses and for practicing engineers who need an up-to-date reference text.
The crucial idea unifying different parts of this book is Danish physicist Niels Bohr’s quotation “Nothing exists until it is measured.” Such profoundly engineering approach let pave the way to microscopic Maxwell’s equations by forsaking the traditional historically ordered development for a more logical and less coarse axiomatic methodology based on Lorentz’s force equation and Gauss’s conservation laws.
With the rapid growth of wireless technologies, more and more people are trying to gain a better understanding of electromagnetics. The theories and methods presented in the book are foundations of antenna applications, wireless engineering and coming 5G platform, microwave and millimeter wave techniques, optoelectronics and optical fiber communication. This book is designed to present the fundamental concepts of an electromagnetic field theory of the fundamental interactions of electromagnetic waves and materials such as ferro- and ferrimagnetics, artificial dielectrics, superconductors, metamaterials, graphene, artificial impedance surfaces. It bridges the gap between electrodynamics and circuit theory through the reflection coefficient concept, and Smith chart introduction demonstrates how to apply these concepts to a wide range of applications. The material presentation style in the book is generally towards a tutorial.
The book is organized into 9 chapters, appendix, and index with short reference material in each chapter.
