This paper proposes a novel time domain numerical scheme based on a modified finite‐difference time‐domain (FDTD) method for electromagnetic interference (EMI) analysis of braided cable networks. In this method, a reasonable physical boundary condition is constructed by a transfer impedance model, while the spatial fields can be applied by way of adding incentive items into the transmission line equations. Besides, the full‐wave finite‐difference time‐domain(2, 4) method with thin wire model, transmission line equation and the modified nodal analysis are combined in order to solve cable‐interconnect line network transient responses in the problem of field‐line‐circuit union simulation. This method has good agreements with HSPICE. In addition, the method is used successfully in analyzing a cable‐interconnect network with different shielding characteristics.
