In this paper,an efficient multi-conductor simplification technique is proposed to model the electromagnetic immunity on cable bundles within a braid shielding structure over a large frequency range.By grouping together the conductors based on the knowledge of Z-Smith chart,the required computation time is markedly reduced and the complexity of modeling the completely shielding cable bundles is significantly simplified with a good accuracy.After a brief description of the immunity problems in shielding structure,a six-phase procedure is detailed to generate the geometrical characteristics of the reduced cable bundles.Numerical simulation is carried out by using a commercial software CST to validate the efficiency and advantages of the proposed approach.The research addressed in this paper is considered as a simplified modeling technique for the electromagnetic immunity within a shielding structure.
