electromagnetic coupling

When your circuit misbehaves with unexplained noise and jitter, you're facing electromagnetic coupling. This practical guide walks engineers through identifying whether problems stem from differential or common mode issues, near-field or far-field effects, and provides a systematic debugging workflow to isolate sources, paths, and receivers—getting your design back on track.

The goal of this paper is to investigate fundamental mathematical and statistical algorithms for the spatiospectral analysis of electromagnetic coupling in large, complex electronic systems. A novel stochastic Green’s function and a statistical representation formula are proposed, which statistically replicates the multipath wave-chaotic dynamics inside cavity environments. The work achieves a physics-based modeling and simulation capability that predicts the probabilistic behavior of high power radio-frequency induced current and voltages in complex electronic systems.
