A comprehensive review of the recent advances in anechoic chamber and reverberation chamber designs and measurements Anechoic and Reverberation Chambers is a guide to the latest systematic solutions for designing anechoic chambers that rely on state-of-the-art computational electromagnetic algorithms. This essential resource contains a theoretical and practical understanding for electromagnetic compatibility and antenna testing. The solutions outlined optimise chamber performance in the structure, absorber layout and antenna positions whilst minimising the overall cost. The anechoic chamber designs are verified by measurement results from Microwave Vision Group that validate the accuracy of the solution. Anechoic and Reverberation Chambers fills this gap in the literature by providing a comprehensive reference to electromagnetic measurements, applications and over-the-air tests inside chambers. The expert contributors offer a summary of the latest developments in anechoic and reverberation chambers to help scientists and engineers apply the most recent technologies in the field. In addition, the book contains a comparison between reverberation and anechoic chambers and identifies their strengths and weaknesses. This important resource: - Provides a systematic solution for anechoic chamber design by using state-of-the-art computational electromagnetic algorithms - Examines both types of chamber in use: comparing and contrasting the advantages and disadvantages of each - Reviews typical over-the-air measurements and new applications in reverberation chambers - Offers a timely and complete reference written by authors working at the cutting edge of the technology - Contains helpful illustrations, photographs, practical examples and comparison between measurements and simulations Written for both academics and industrial engineers and designers, Anechoic and Reverberation Chambers explores the most recent advances in anechoic chamber and reverberation chamber designs and measurements.

    An anechoic chamber (AC) is a large room lined with radio absorbing materials (RAMs) on the walls, floor and ceiling to simulate a free space environment. It has been used in antennas, radar, and Electromagnetic Compatibility (EMC) areas for many years, but the design of an AC is a challenging system-level problem, involving different companies such as those producing RAMs, antennas or mechanical control systems. The anechoic chamber has been used in the RF and microwave industry for many years. This book provides the latest systematic solutions for anechoic chamber design using state-of-the-art computational electromagnetics algorithms. The objective is to maximize the chamber performance and minimize the overall cost. The AC designs are verified by measurement results from Microwave Vision Group (MVG) which validate the accuracy of the solution. Reverberation chambers (RCs) were originally developed for Electromagnetic Compatibility (EMC) measurements. Over the past few years the application area has been extended greatly, from antenna measurements to communication channel emulation. It is believed in some applications that using an RC is much better than using an AC. The number of published papers in the new applications of the RC has increased significantly, but currently there is no relevant book in this area to summarize the latest advances to help people to apply these methods in practice. This book will fill this gap and provide a relatively comprehensive reference for radio frequency (RF) engineers and EMC engineers to use these chambers with the latest technology, covering a series of the latest measurement methods in the RC. These two chambers are essential measurement facilities for antennas and EMC measurements. It will be shown that they are closely related; for example, both of them can be used for antenna efficiency, and radiated emission and immunity measurements. Comparison between them will be made to identify their advantages and disadvantages.
