A predictive time-domain (TD) analysis of near-field (NF) coupling for complex shape wiring system is reported. Based on the Taylor model, methodological approach enabling to determine the transient voltage coupling induced by electromagnetic (EM) near-field action on the metallic wiring structure is presented. The basic steps indicating how the coupling time-dependent voltages were calculated are described. The feasibility of the TD calculation method under study was confirmed by investigating the NF coupling between 200-mm I-shape wire as a radiating culprit and Z-shape victim wire of 60mm distance. An arbitrary form pulse having 40-ns-time-width was considered as transient perturbation. Comparison between the time-dependent voltages calculated across the victim wire extremities and full wave simulations performed with a commercial tool is addressed. The potential application of the proposed method notably for EMC characterization is discussed.
