Dr. Vignesh Rajamani of Rhode & Schwarz

The complexity of modern electronics in automobiles, necessitates meticulous EMC testing to ensure that these components can coexist without causing or experiencing disruptive interference. ISO 11451-1 specifies general test conditions, definitions, practical use, and basic principles of a Vehicle test for electrical disturbances from narrowband radiated electromagnetic energy and part 5 holds specifics for full vehicle testing in reverberation chambers. In this presentation, general reverberant test techniques will be discussed along with advantages and disadvantages of the newly proposed test techniques in the standard. 

Biography:

Dr. Vignesh Rajamani is an expert in the electromagnetic characterization and application of reverberation chambers. A main thrust of his research and project experience in the area of reverberation chambers has been towards increasing test accuracy. His expertise includes statistical electromagnetics, validation and optimization techniques for computational electromagnetics, communication system testing 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.  In his previous role as a Manager at Exponent, he assisted clients with identifying the root cause of the failures of electronic systems and providing guidance on possible solutions, especially in the area of EMI/C.  Dr. Rajamani is the Immediate Past President of the IEEE Electromagnetic Compatibility (EMC) Society and involved with several technical committees and educational activities in the EMC Society and its sister societies.  He served as the President of the IEEE Electromagnetic Compatibility (EMC) Society for the years 2022 and 2023. Before that he was the Vice President of Member Services for the IEEE EMC Society from 2014-2020. He also chaired the International Symposium on EMC+SIPI in 2024. 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. He is also the Secretary for the Transportation and Electrification Council under IEEE and the Chair of the Events Innovations and Enhancement working group on Industry Engagement.  Prior to joining Exponent, Vignesh 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. He has also taught the reverberation chamber course at OSU for the past 10 years and served as subject matter expert for various standard bodies.  In his current role, he is working as a Manager for EMC Strategy and Business Development for Rohde and Schwarz.  Rohde & Schwarz develops, produces and markets a wide range of electronic capital goods for industry, infrastructure operators and government customers. The independent group is among the technology and market leaders in all of its business fields, including wireless communications and RF test and measurement, broadcast and media, air traffic control and military radiocommunications, cybersecurity and network technology.
