This paper provides a comprehensive study on how to mitigate desense with the change in the spectrum distribution by tuning the duty cycle of the interfering clock. Measurements conducted on a real cellphone showed a 10 dB suppression of desense for certain TX bandwidth condition.

Bias tees are an important tool for many applications including vector network analysis. As accurate understanding and modeling of power electronic components becomes increasingly important for the study of their electromagnetic emissions, so do broadband measurements with bias tees. This paper describes the composition of such a special bias tee in terms of the necessary geometries and circuitry.

CISPR Publications 24 and 35 allow radiated and conducted immunity tests to be performed using I% or 4% steps. This article looks at measured radiated immunity test data to determine the typical shapes of radiated susceptibilities for multimedia equipment. The authors consider what those shapes tell us about the validity of the 4% step method.

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 authors predict the internal electromagnetic field of a populated enclosure by using the diffusion model, and compare them with the fields obtained by the power balance method, a full-wave electromagnetic solver and measurements, to demonstrate its efficacy.

Accredited test laboratories, complying with the requirements of ISO/IEC 17025 have to evaluate measurement uncertainty.

Statistical model-based EMC design is evolving for complex electronic networks installed in enclosed spaces typical of spacecraft, aircraft and automobiles.
