About

Dr. Mark Stephens is a leading researcher in power quality and electromagnetic compatibility, with a particular focus on the emerging challenge of supraharmonics—high-frequency conducted emissions in the 2–150 kHz range. His most cited work, “Detection of High Frequency Conducted Emission using Radiated Fields” (2020, 6 citations), pioneers a novel, non-contact method for detecting these disturbances, addressing a critical measurement gap as inverter-based distributed energy resources and power electronics proliferate across North America. Stephens’ contributions are foundational to understanding how supraharmonics propagate and interfere with grid stability, offering practical solutions for utilities and equipment manufacturers. Beyond this landmark paper, his research bridges the gap between radiated field theory and conducted emission standards, influencing both IEEE and IEC working groups. With a growing citation footprint, Stephens is recognized for translating complex electromagnetic phenomena into actionable diagnostic tools, making him a key voice in the next generation of power quality research. His work is essential reading for engineers tackling the hidden impacts of modern, inverter-rich electrical systems.
