Understanding Microwaves / Edition 1

A complete and accessible introduction to the important field ofmicrotechnology

Understanding Microwaves covers all the important microwaveterminology, devices, and systems, and provides an understanding ofhow everything fits together to make communications, navigation,and radar equipment. The text is geared toward engineers new to themicrowave industry, as well as technicians, managers, and students.This field-tested book presents material the author has used inindustrial training courses for thousands of students. It is easyto understand and avoids complex mathematics. With extensiveexercises at the end of each chapter, and answers at the end of thebook, it is suitable for self-study or as a text for industrialseminars and college courses.

First, the coverage details the special language of microwaves.Then, it outlines all of the unique devices that are used inmicrowave equipment and explains how these types fit together tomake a typical microwave system, describing what they do, how theywork, and what their important performance characteristics are.Finally, the book covers all of the important types of microwavesystems, including their structure, function, and applications.Understanding Microwaves is a complete introduction to thisimportant field.
