Enhanced Transmission Model for Predicting Coupling Between Electromagnetic Field and a Twisted-Wire Pair of Complex Dielectric Coatings

Abstract

In this paper, an enhanced electromagnetic field coupling to twisted wire pair (TWP) model is developed and applied for predicting the terminal voltage/current responses. In contrast to the classic transmission line (TL) model, the proposed approach takes account the perturbation effect on external field due to the presence of coatings by assigning a weight (coating coefficient Cd) to the source terms contributed by transversal field component. The case study shows a significant improvement of the modeling accuracy with respect to classic TL model.
