Interference

Answering the needs of managing EMI in actual use, this article provides hands-on guidance to specialists at the factories and elsewhere on measuring conducted EMI where it matters – in their environment. Anyone who knows how to use an oscilloscope can perform such measurements.

Ever tried to measure low-level signals in the presence of noise? Or wanted to capture a measurement isolated from ground, like that of an ungrounded hand-held digital multi-meter, but also needed to capture finer details of the signal, like those captured with an oscilloscope?

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.

The Banana Skin columns were compiled by Keith Armstrong, of Cherry Clough Consultants Ltd, from items he found in various publications, and anecdotes and links sent in by the many fans of the column.

Are you just getting into software simulation and feeling a little overwhelmed with all the new jargon? This brief article will explain some of the most common terms used in the very exciting world of EMC/Signal Integrity simulation software, all in one location.
