Abstract : This work proposes a mathematical transformation for the sources and the linear loads to overcome the cable-load connection restrictions applied to a braided shielded cable in the combined MoM/MTL approach. When the assumptions of the transmission line theory are nonvalid because of a non-direct current flowing below the shielded cable, numerical techniques for solving EMC problems have to be deployed. The proposed model is based on an association of voltage sources and current-controlled voltage sources to reproduce the behavior of the real sources and loads at the terminations of a shielded cable. In order to validate this approach, a measurement setup has been proposed to take into account the influence of a non-direct current flowing through a ground plane with a large aperture. The measurement results obtained between 10 kHz and 300 MHz, where the main radio reception EMC issues exist, have been compared to the combined MoM/MTL modified approach. The excellent comparison results prove that combining full-wave numerical techniques and the proposed mathematical transformation can overcome the cable-load conditions in complex electromagnetic environments.
