Introduction to Electromagnetic Theory

About the Book

The present book Introduction to Electromagnetic Theory is written under the CBCS pattern, followed by all Indian Universities guided by UGC. This book is the result of great attempts by the authors to bring a balance between the mathematical framework and the conceptual development from the theoretical point of view. This text book will help the undergraduate students to build a solid conceptual base in the field of classical electrodynamics, which will help them to explore the beauty of man's thought process in this particular branch of physics. The ideas will help the engineering students to apply the different laws of this branch in different applications. The book is started with a brief introduction about the EM theory. In the first chapter, authors briefly discussed different mathematical tools and their relations with the many physical concepts used in the rest of the book. This first chapter is very important for the journey to the rest of the book. The second chapter starts with the Gauss’ law for electric fields, magnetic fields and then the Faradays law and Ampere's law in non-stationary states. The authors then discussed how Maxwell explored the incompleteness of the Ampere's circuital law and then make it modified to relate it with different electromagnetic phenomena occurred in nature. In this chapter, Maxwell's equations expressed both in the integral and differential forms are presented using different mathematical tools which were already discussed in the first chapter . In the third chapter, authors focused their discussions to the different laws of conservations which are obeyed by the EM waves during its propagation in a medium. Fourth and fifth chapters are dedicated on the propagation of EM waves in unbounded and bounded media respectively. In chapters six and seven they presented the different EM phenomena observed in nature due to the anisotropy behavior of a medium. The content of the last two chapters are related to the brief introduction to two well established applications of EM theory, namely optical waveguide and fiber optics. Authors appreciate any kind of feedback from the students as well as from the experts of any discipline, whatsoever, about the book.
