“…The Discrete Complex Image Method (DCIM) [1]- [5] is widely used in transforming the spectral-domain multilayered Green's function into spatial domain. It works well in most occasions, but as shown in [6], the DCIM can not work well in the shielded structure problems.…”

The improved GE method has been used to evaluate the spatial-domain Green's function of the shielded structures. However, for some cases, the spectral-domain Green's function decays slowly and is very difficult to be accurately approximated by the GPOF used in the improved GE method. This subsequently deteriorates the accuracy and stability of this method. In this paper, we devise a scheme that the GPOF is applied for multiple times to approximate the spectral-domain Green's function. Numerical results have shown that the spectral-domain Green's function can be better approximated and thus the accuracy of spatial-domain Green's function is improved.

An efficient and rigorous method for the analysis of planarly layered geometries with vertical metallizations is presented. The method is based on the use of the closed-form spatial-domain Green's functions in conjunction with the method of moments (MoM). It has already been demonstrated that the introduction of the closed-form Green's functions into the MoM formulation results in significant computational improvement for the analysis of planar geometries. However, in cases of vertical metallizations, such as shorting pin's, via holes, etc., there are some difficulties in incorporating the closed-form Green's functions into the MoM formulation. In this paper, these difficulties are discussed and their remedies are proposed. The proposed approach is compared to traditional approaches from a theoretical point of view, and the numerical implementation is demonstrated through some examples. The results are also compared to those obtained from the commercial software em by SONNET. Index Terms-Closed-form Green's functions, generalized pencil of function method, method of moments, planarly layered media.
