A robust generalized DCIM technique with pole extraction

Abstract

A generalized discrete complex image method (DCIM) technique with an improved range of the spatial Green's function was presented by extracting the poles contributions and using additional synthetic poles as the quasi-static image for the surface wave poles. The technique includes an algorithm and can be applied to the Green's functions of other geometries such as multilayered cylindrical structures. It was shown that the computational requirement of the algorithm was approximately equal to that of evaluating only one contour integral regardless of the number of poles to be extracted.
