The Use of Tansfinite Elements in the Methods of Moments Applied To Electromagnetic Scattering By Dielectric Cylinders - Abstract *

Abstract

Many electomagnetic applications involve the analysis of the scattering of an electromagnetic wave by a dielectric body. This kind of problem is often carried out using the method of Moments (MoM) applied to volume or surface integral equations. Unfortunately, this method seems unreliable in certain cases. In this paper, to evaluate this problem, we developed a two-dimensional MoM based on the volume-surface integral equation and employing the transfinite elements theory which provides a powerful tool to study separately the effects of the geometrical modeling and those of the interpolation schemes for all the methods (cell shapes and interpolation schemes) encountered in the conventional MoM.
