A practical one-volume guide to anechoic chamber designs for electromagnetic measurements The electromagnetic anechoic chamber has been with us since it was invented at the Naval Research Laboratory in Washington, DC, in the early 1950s. Just about every major aerospace company has large numbers of them located throughout the United States and the world. Now, because of the stringent electromagnetic interference requirements that must be considered in the development of all new electronic products, these facilities are appearing in the automotive, telecommunications, aerospace, computer, and other industries. This handbook provides the designer/procurer of electromagnetic chambers with a single source of practical information on the full range of anechoic chamber designs. It reviews the current state of the art in indoor electromagnetic testing facilities and their design and specifications. You'll find information on a large variety of anechoic chambers used for a broad range of electromagnetic measurements that are commonly conducted in indoor test facilities as well as details on: * Measurement theory to support the chamber design procedures provided in each of the specific chamber designs * Test facilities for the measurement of antennas, scattering (RCS), and electromagnetic compatibility * An extensive set of photographs, including a special color section highlighting some of the more interesting anechoic test facilities that have been built to solve various measurement problems * Design/procurement checklists

As technologies for wireless communications, including 5G and Internet of Things (IoT), require more complex antennas, practitioners need more information on the best methods to perform measurements on these different types of antennas. This exciting resource provides guidance on the proper design of indoor ranges for RF antenna measurements. The important aspects of specifying the range or resources needed in a development program are explored. Analysis of existing ranges to determine their suitability for performing specific test that a user of the range may require is also introduced. Readers find in-depth coverage of the design of ranges and how to evaluate the error contributions of the range and the best approach to measure a system, antenna, or other radiating hardware. The book provides information on selecting the right range to make a specific type of measurement and understanding for an RF absorber. Matlab scripts are also included to help readers estimate the performance of an RF absorber. Readers will be able to estimate the required space for a given type of measurement, as well as identify what type of range is the better choice, based on physical limitations and economics. Simple rules for the design of an anechoic chamber, based on the required accuracy and parameters to be measured are described. Packed with examples and references, this book is a prime reference for any practitioner that uses or designs facilities for the measurement of electromagnetic energy.
