A complete and accessible introduction to the important field of microtechnology Understanding Microwaves covers all the important microwave terminology, devices, and systems, and provides an understanding of how everything fits together to make communications, navigation, and radar equipment. The text is geared toward engineers new to the microwave industry, as well as technicians, managers, and students. This field-tested book presents material the author has used in industrial training courses for thousands of students. It is easy to understand and avoids complex mathematics. With extensive exercises at the end of each chapter, and answers at the end of the book, it is suitable for self-study or as a text for industrial seminars and college courses.

The book is organized into four parts, based on descriptions of objects at four different levels of abstraction.
1. Generalized images-images and image-like entities.
2. Segmented images-images organized into subimages that are likely to correspond to "interesting objects."
3. Geometric structures-quantitative models of image and world structures.
4. Relational structures-complex symbolic descriptions of image and world structures.

The parts follow a progression of increasing abstractness. Although the four parts are most naturally studied in succession, they are not tightly interdependent. Part I is a prerequisite for Part II, but Parts III and IV can be read independently.

The two-volume World of Forensic Science is a convenient, comprehensive guide to the scientific processes and the legal, social and ethical issues involved in the forensic sciences.
