Susceptibility analysis of wiring harness in a reverberation chamber environment

In this work, the external susceptibility of a wiring harness in a reverberation chamber is investigated, and described from a statistical viewpoint. The electromagnetic field generated in the chamber environment is modeled as an integral of plane waves with random amplitude, phase and polarization. The wiring harness is modeled as a uniform and lossless multiconductor transmission line (MTL) with resistive loads. Closed form expressions are derived for statistical estimators (mean value, variance, and probability density function) of the circuit quantities (current, voltage, and power) induced by the impinging field in the line loads. Results obtained in this work for the susceptibility of a MTL in a reverberation chamber are in agreement, and extend the general properties derived in previous works
