Abstract

This paper presents an efficient technique for analysis of arbitrary closed perfectly conducting (PEC) scatterers in layered media. The technique is based on a method of moments (MoM) solution of the combined field integral equation (CFIE). The high efficiency is obtained by employing an accurate expansion of the multilayer dyadic Green´s function along with a higher order hierarchical discretization scheme and a rapidly converging iterative solver with preconditioner.
