Waveguides
Waveguides as the name implies guide the electromagnetic waves from one point to the other. The electromagnetic wave is repeatedly reflected from opposite walls of the guide and is carried from one end to the other end in an zigzag path.

Preface
Engineering electromagnetics is an interesting subject in the electrical/electronics engineering curriculum. However, students find it difficult to grasp the concepts and usually complain the paper is tedious. The common conception about electromagnetics is that the subject is hard to understand and is not as beautiful as other papers. As an example, mechanics appears to be friendlier to students. Concrete concepts and dealing with tangible objects make the learning of mechanics simple for students. Studies on projectile thrown in space, an object sliding on a floor, can be clearly visualized. On the contrary, electromagnetics is characterized by abstract concepts and intangible fields. Along with complex mathematics, imperceptible concepts and invisible fields confuse the students, and understanding electromagnetics becomes a dream for the reader. An attempt has been made in this book to change the above scenario. Real-life examples have been used throughout the book for easy grasping of the abstract concepts. This book is a result of a decade of teaching electromagnetics for electrical/electronics engineering students and physics postgraduates. Motivated by the positive feedback from students for the simple and lucid form of presentation of the subject, a need was felt to turn the presentation
