Presentation 1: Introduction to Reverberation Chambers

By Mr. Garth D’Abreu, Director of RF Engineering, Test Solutions Group, ETS-Lindgren, Cedar Park, Texas

Abstract: Reverberation chambers were once primarily used for military and automotive testing. Today, they are also increasingly used for new and diverse applications due to their inherent efficiency and cost effectiveness. New applications include aircraft testing, simulating a wireless environment, probe calibration, and determining the shielding effectiveness of materials and components such as cables and connectors, to name just a few. The presentation will provide an overview of reverberation chamber fundamentals and applications. A comparison of cost and performance tradeoffs of testing in an anechoic chamber versus a reverberation chamber will be provided.

Presentation 2: Application of Reverberation Chamber Methods in Aerospace

By Dr. William O. Price, Technical Fellow, Boeing Military Aircraft/Boeing Defense, Space & Security, Seattle, Washington

Abstract: Following a brief survey of the development of reverberant chamber theory in the US government and industry, Dr. Price will share several case studies of reverberation chamber measurements and the extension of those methods to measurements in electrically large cavities in aerospace products.

Presentation 3: Reverberation Chamber Test Techniques in RTCA/DO-160

By Mr. Dave Walen, Chief Scientific and Technical Advisor – Aircraft Electromagnetic Compatibility (EMC) FAA Aviation Safety, Seattle, Washington

Abstract: Mr. Walen will describe the history and application of reverberation techniques in RTCA document DO-160, particularly related to RF susceptibility and RF emissions tests for aircraft equipment. He will discuss the relationship of these test techniques to reverberation techniques used to characterize aircraft RF attenuation.


Mr. Garth D’Abreu, Director of RF Engineering, Test Solutions Group with ETS-Lindgren, has primary responsibility for the design and development functions within the RF engineering group. The RF group provides technical support for ETS-Lindgren worldwide and is responsible for anechoic chambers, E Field generators, TEM cell device design and development, antenna design and absorber development. Mr. D’Abreu is the lead engineer for reverberation chamber design and testing and is responsible for the development of GTEM cells, products for EMP applications and wireless device test systems. He holds a BSc degree in Electronics & Communications Engineering, North London University, UK. He is a member of the IEEE EMC Society and has over 20 years of experience in the RF industry.

Dr. William O. Price (M’75) received the B.S. degree in electrical and computer engineering from Oregon State University, Corvallis, in 1975, the M.S. degree in electrical engineering from California State University, Northridge, in 1976 and the Ph.D. degree at Griffith University, Brisbane, Qld., Australia in 2009. From 1975 to 1987, he was with the Naval Air Systems Command, Pacific Missile Test Center, Pt. Mugu, CA where he was a senior EME engineer. Since 1987, he has been with Boeing Company, Seattle, WA, where he is currently a Technical Fellow in the Boeing Military Airplanes Division and practices the art of electromagnetic effects engineering. He currently serves industry as an officer of the IEEE EMC Society’s Technical Committee 5 (TC-5) on High Power Electromagnetics.

Mr. David Walen is the Chief Scientific and Technical Advisor – Aircraft Electromagnetic Compatibility with the Federal Aviation Administration. Dave specializes in aircraft electromagnetic compatibility, lightning protection, and high intensity radiated field (HIRF) protection. He is involved in FAA aircraft certification, accident investigation, electromagnetic protection policy development, and aircraft electromagnetic protection certification training. Dave joined the FAA Aviation Safety organization in September 1996 as Chief Scientific and Technical Advisor for Aircraft Electromagnetic Compatibility. Dave serves on RTCA Special Committee 135, which prepares aircraft equipment environmental test procedures in document DO-160. He is a long-time member of the SAE AE2 Lightning committee, setting aircraft lightning protection standards. He was co-chair for the SAE AE4 High Intensity Radiated Fields (HIRF) working group which prepared aircraft HIRF certification and test guidance in ARP5583A. He also co-chaired the working group of RTCA Special Committee 202 which prepared aircraft standards for demonstrating tolerance to portable electronic devices in DO-307. Prior to joining the FAA, he spent nineteen years with the Boeing Company, where he was an engineer and manager working on civil and military aircraft HIRF protection, lightning protection, and antenna engineering.
