Electromagnetic Radiation Resulting From PCB/High-Density Connector Interfaces

Professor Clayton Paul made many contributions to the field of electromagnetic compatibility as a researcher, teacher, and mentor. Among these contributions, he provided a seminal push in characterizing, understanding, and quantifying the coupling and radiation physics of electromagnetic interference (EMI). An overview of these original contributions that were driven by industry problems and needs is given here. His work emphasized physics and formulation in order to provide quantitative solutions and design directions. These ideas are applied to a current industry challenge in understanding and quantifying EMI that results at the interface between high-speed, high-density connectors and printed circuit boards.
