Abstract: The use of the Friis transmission equation is crucial in understanding the propagation of electromagnetic energy from a source to a receiver. It relates the power received by an antenna to the power transmitted from another antenna, considering the distance between them and the frequency of the signal. This equation has applicability to the successful development of wireless communication systems (including antenna design) and can be used to provide insight into the interaction between unintentional radiators and/or receivers of energy that is the root-cause of many EMC issues. The physics and mathematics of the Friis equation will be discussed and its effects will be demonstrated.

Biography:

Mark A. Steffka, recently retired from his position as a full-time faculty member of Electrical and Computer Engineering department at the University of Detroit – Mercy. His responsibilities there (and previously at the University of Michigan – Dearborn) included teaching undergraduate, and graduate courses on electrical/electronic circuit design, electromagnetic compatibility (EMC), antennas, and electronic communication systems.  He has over 40 years of industry experience with military HF/VHF/UHF secure communications, spacecraft instrumentation, automotive electrical/electronic system design and EMC, vehicle antenna systems, and industrial electronics. He has served a number of times as the SAE World Congress Automotive Electronics Session Chair, was the General Chair of the 2023 IEEE International Symposium on Electromagnetic Compatibility and Signal Integrity/Power Integrity, and is completing his second 3 year term as a member of the IEEE EMC Society Board of Governors.
