Abstract The integration paths and the expansion functions in two-level DCIM are investigated. Accurate
expansion functions are proposed and a novel integration path, which can be used to calculate the spatial Green’s functions of microstrip structure, is presented. The spatial Green’s functions of a five-layer microstrip structure are calculated, and the results show the effectiveness of the proposed method.
