Abstract

A fast hybrid time-domain method for analyzing electromagnetic coupling into enclosures through imperfectly-shielded coaxial cables is described. The method computes fields on complex and multiscale structures, including platform-installed shielding enclosures, antennas, printed circuit boards, coaxial cables, and cable connectors/loads by employing three different solvers: (i) a time-domain integral-equation based FFT-accelerated parallel field solver, (ii) a finite-difference time-domain based cable solver, and (iii) a modified nodal analysis based circuit solver. These solvers are coupled at the cable connectors/loads and shields; the resulting coupled system of equations is solved simultaneously at each time step. The proposed method is used to analyze cable-induced coupling to PC cards located in a shielding enclosure.
