A Hybrid Time-Domain Maxwell/MTLN-Equations Method to Simulate EM-induced-Currents on Electric Cable-Bundles Inside Cavities

Abstract

This paper proposes a time-domain hybrid method for coupling Multiconductor-Transmission-Line Network equations and a Finite Element Method to evaluate the electromagnetic response of the electric wires of a cable-bundle located inside a 3 dimensional structure. The method is applied and demonstrated over a box structure made of several volumes containing a realistic multiconductor cable-harness and illuminated by a plane wave. The formalism of the method is given and the results obtained show the interest of this approach.
