Preface

Electromagnetic Field Theory and Transmission Lines is a core subject for all the students of BE/BTech in Electronics and Communication Engineering, Electronics Engineering, Electrical Engineering, Electronic Instrumentation Engineering, MSc (Electronics), MSc (Applied Physics), AMIETE, AMIE, and other courses throughout the world. EMF theory is essential for the design and analysis of all communication and radar systems. Moreover, it has numerous applications in all fields of life. It is a universal theory and has many advantages over the circuit theory which has limited applications. It is also useful in biomedical engineering in connection with radiation therapy. It is extremely useful to interpret electromagnetic interference in the systems for compatibility studies. The behaviour of electromagnetic waves between the transmitter and receiver can be understood only with the concepts of the electromagnetic field (EMF) theory.

I have been teaching this important subject for several years, referring to books written by several experts like Kraus, Jordan, Hayt, Kreyszig and Narayana Rao. However, the general belief is that no single book available caters to the needs of a complete course required for undergraduate and post graduate programmes. In view of this, an attempt is being made to bring out a simplified book on the subject of Electromagnetic Field Theory and Transmission Lines.

I hope that this book will be extremely useful for students, teachers, professionals, engineers, technicians, designers and also for short-term course organisers.

Any suggestions to improve the book will be welcome.
