A Probabilistic Approach for the Susceptibility Assessment of Twisted-Wire Pairs Excited by Random Plane-Wave Fields

Abstract

This paper presents a probabilistic approach for the susceptibility assessment of a twisted-wire transmission line in the presence of a plane-wave electromagnetic field with certain parameters (amplitude, polarization angle, direction-of-incidence angles) treated as random variables. The transmission line is located in free space and terminated in arbitrary loads. Closed-form expressions are provided for the probability density function of the induced far-end voltage in certain cases of field descriptions and excitation scenarios. A more general Monte-Carlo technique is also employed, in order to cope with cases yielding laborious integrals.
