Overview:
This textbook covers the fundamental concepts of static and dynamic electromagnetic fields and waves. It is designed to
serve as a textbook for the course on ‘Electromagnetic Theory’ taught to electrical, electronics and communication
students in all engineering institutions in India. Its comprehensive approach to the subject and simple presentation will
help students to grasp complex topics with ease.
To make this book easily comprehensible and student friendly, the authors have organized the topics in a logical
progression. This will allow students to first work with electromagnetic concepts involving relatively simple
computational analysis and then move on to more complex topics and mathematical methods for analysis. In keeping
with this student-friendly approach, the book begins with an introduction to complex vectors and Maxwell’s equations
and then moves on to discuss advanced topics such as uniform plane waves, waveguides and resonators, transmission
lines, antennas, Rayleigh scattering, holography, Doppler’s effect, electrostatic and magnetostatic fields, direct currents,
solution techniques of Poisson and Laplace equations, and electroquasistatic and magnetoquasistatic fields. Each of
these topics has been adequately covered in accordance with its relevance to the subject, making it a complete textbook for
students.

Interview with Rakesh Singh Kshetrimayum
Overview :
ISBN : 9788131516584
Pages: 402
Electromagnetic Field Theory aims to give a solid foundation on electromagnetic
fields, waves, and radiating systems. It is targeted as a textbook for electromagnetic
field theory course for undergraduate electronics engineering students. Besides strong
fundamentals on Maxwell’s equations, this book provides in-depth discussion about
the basics of electromagnetic waves (wireless communication channel modeling
requires this knowledge), transmission lines (microwave engineering course requires
a background of this topic), and antennas (antenna is a component of any
communication system; any communication cannot happen without this).
1.
What is the target market for this book?
This book can be used as a textbook for electromagnetic field theory course for senior undergraduate or first year graduate
students. It may be used as a reference for anyone (physicist or engineer) who wants to explore electromagnetic theory.
2.
Why did you write this book?
Electromagnetic field theory is considered to be one of the toughest subjects by many students. The aim of this book is to
make it easier for them by employing many pedagogical methods.

Do you see any change in the way the course has to be taught?
A proper revision on the vector analysis is a must before getting into electromagnetic field theory. Next, a sound
understanding of all four Maxwell’s equations should be developed. After that only, one should explore electromagnetic
waves, radiation, numerical electromagnetics, etc., in depth.

First figure in a chapter usually depicts what topics you are going to learn in that chapter and how they are interlinked. Last
figure in the chapter (before the exercise) is usually chapter in a nutshell (one single diagram with all the topics and
corresponding important equations). You may use this diagram for easier revision purposes (all these chapters in a nutshell
figures are listed in Appendix B again).

You should try to solve examples inside the text by yourself without looking at the solutions. See the solutions only if you
can’t solve them. You should try to solve exercise problems. If you can’t solve them, ask your instructor for solutions.
Multiple choice questions at the end of each chapter are meant for testing your understanding on the chapter. Check if you
can answer all of them correctly.

1.
All important equations should be derived in the class without skipping any of the steps involved and explain clearly the
physical interpretations after the derivations. This way, students feel that they know more about those equations.
2.
In order to enhance interest in very abstract course such as electromagnetic field theory, an instructor should discuss in brief
about the various applications of the theory they learn in the class. At appropriate places, students should be encouraged to
do some simulations of fields, waves, and radiation. Some MATLAB based examples are provided in the book, instructor
may add more of them if he/she feels it is necessary.
3.
Senior undergraduate or first year graduate students usually have some exposure to electromagnetic fields, so, depending on
the background of the students in the class, an instructor may compress the portion up to Maxwell’s equations and spend
more time on topics such as electromagnetic waves, antennas, waveguides, etc., which are completely new for the students.
