To study the susceptibility of these cables due to external electromagnetic (EM) perturbation, several numerical methods have been developed. This paper describes a technique for obtaining integrated near-field (NF) coupling Partial Element Equivalent Circuit (PEEC) model for the electromagnetic compatibility (EMC) issues. It incorporates EM coupling due to electronic components and cables with/without ground plane along with its capabilities of transforming field based problem into the circuit domain. Elementary dipoles are used to calculate the EM field, which represents modeling of electronic components radiation. The proposed approach is demonstrated by analyzing a cable above the ground plane and with elementary dipoles as source of disturbances. It is being carried over with Finite Element Method (FEM) and then Finite Integration Technique (FIT). The results obtained by both the methods are in good agreement. In order to validate the obtained results, the test set up is being built by analytical TLM models. The developments of 2D and 3D dimensional dipole are being integrated into the PEEC method. As perspective, coupling PEEC model could be developed considering inductive and capacitive coupling between the cable, ground plane and devices.
