Scattering characteristics analysis of chiral bodies with generalized transition matrix

In this paper, the electromagnetic scattering of chiral body is analyzed by the newly developed generalized transition matrix (GTM). The scattering characteristics of a chiral body is represented as a GTM which describes the relationship between incident fields and scattered fields on a reference surface. The chiral body´s scattered fields which are previously calculated by the method of mements (MoM) with Schaubert-Wilton-Glisson (SWG) basis functions based on volume integral equations (VIE) and volume meshes can be now calculated by Rao-Wilton-Glisson (RWG) basis functions based on surface meshes, thus reducing the number of unknowns and analyzing complexity in a large system.
