This book covers important and timely issues in Reverberation Chambers (RCs) and their applications to EMC and Antenna measurements. Developed specifically for university students, researchers, practicing industrial engineers and designers who work with antennas in radio frequency (RF) engineering, EMC, radar, and radio communications. This book will provide the reader with a firm theoretical and practical understanding of the RCs operation, allowing them to undertake practical antenna and EMC measurement work with confidence and accuracy. The book is built on many years of research by the authors that encompass many of the new advances in antenna design.
