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 Greens functions of microstrip structure, is presented. The spatial Greens functions of a five-layer microstrip structure are calculated, and the results show the effectiveness of the proposed method. -
