Comparison between the Kummer's transformation and Ewald method for the evaluation of the parallel plate Green's functions
2006
In this paper, we present a convergence and efficiency study of two different acceleration techniques for the evaluation of the parallel plate Green's functions. The first technique is based on the extraction of the asymptotic terms of the spectral representation of the parallel plate Green's functions by applying the Kummer's transformation. The second technique is a straightforward reformulation of the 2-D Green's functions for 1-D periodic structures to the parallel plate case. The PPW Green's functions calculated by the two methods have been successfully applied to the analysis of a practical inductive microwave filter containing metallic and dielectric posts. The filter analysis techni…
Efficient software tool for the analysis of planar-based metamaterial structures
2007
We present a software tool specialized in the analysis of metamaterial structures based on planar circuits. The tool implements a formulation for open transversal multilayered structures, which reduces the number of unknowns employed in the problem. Besides, the formulation has been efficiently accelerated by means of a Kummer-like decomposition, extracting the singular behaviour of the Green's functions from the frequency analysis. By means of this formulation, several different kinds of metamaterial structures built in coplanar and microstrip technologies are successfully analyzed, obtaining bandpass and stopband filter responses in a fast and accurate way.
