Dr. Gus Freyer

Gustav Freyer has over 30 years experience in test and evaluation.  For over 15 years he was involved in characterization of the electromagnetic environment in reverberation chambers. He participated in many cavity characterization tests as well as equipment and full system tests.  He participated in the first full aircraft, Hazards of Electromagnetic Radiation to Ordnance, test in a reverberation chamber. He developed a Data Base of approximately 20 reverberation chambers worldwide. He developed this unique course on reverberation chambers and has presented it numerous times both nationally and internationally. He has authored or co-authored numerous papers and technical reports on topics related to reverberation chambers.  Mr. Freyer has a BS Eng., a MS Nuc Eng., and a Ph.D. in Physics.

Dr. Charles F. Bunting

Bunting received the A.A.S. degree in electronics technology from the Tidewater Community College, Norfolk, VA, in 1985, the B.S. (honors) degree in engineering technology from the Old Dominion University, Norfolk, in 1989, and the M.S. and Ph.D. degrees in electrical engineering from the Virginia Polytechnic Institute and State University, Blacksburg, in 1992 and 1994, respectively. From 1981 to 1989, he was with the Naval Aviation Depot, Norfolk, first as an apprentice, then an electronics mechanic, and later an electronics measurement equipment mechanic. From 1991 to 1994, he held a Bradley Fellowship and a DuPont Fellowship. From 1994 to 2001, he was an Assistant/Associate Professor at the Old Dominion University, where he worked closely with NASA Langley Research Center on electromagnetic field penetration in aircraft structures and reverberation chamber simulation using finite element techniques. Since 2001, he is an Associate Professor at Oklahoma State University, Stillwater. His research interests include fundamental variational principles and computational electromagnetics, statistical electromagnetics, electromagnetic characterization and application of reverberation chambers, and the analysis of optical and microwave structures using numerical methods including finite element techniques.

Dr. Vignesh Rajamani

Dr. Rajamani is an expert in the electromagnetic characterization and application of reverberation chambers. His other research interests includes statistical electromagnetics, validation, and optimization techniques for computational electromagnetics, communication system test in complex multipath environments, EMI/C Issues with Unmanned Aerial Systems, antenna systems and radio frequency (RF) design, and estimation probability of failure of electronic systems due to electromagnetic interference and compatibility.

Dr. Rajamani is the Vice President of Member Services for the IEEE Electromagnetic Compatibility (EMC) Society and involved with several technical committees and educational activities through the EMC Society. He is a Senior Member of IEEE and served as a distinguished lecturer for the IEEE EMC Society for term 2013-2014. He has lectured around the world on reverberation chamber test methodologies and has taught design engineering seminars for faculty and students at many universities focusing on challenges in engineering education and prepare the faculty to handle them by spreading a significant number of Project Based Learning (PBL) classes across the curriculum. Prior to joining Exponent, Dr. Rajamani was with Oklahoma State University as a Visiting Assistant Professor where he taught courses in engineering design and performed research in probability of failure of electronic systems in harsh electromagnetic environments.
