Abstract
ABSTRACTScattering of electromagnetic plane waves from normal chiral materials, chiral metamaterials, chiral nihility materials are presented. Based on the volume equivalence principle, the integral equations are represented in terms of a pair of coupled bi-isotropic polarized volume electric and magnetic flux densities. The volume integral equations (VIE) are solved using the method of moments (MoM) combined with tetrahedral mesh. Then the adaptive cross approximation (ACA) algorithm is combined with the fast dipole method (FDM) based on the equivalent dipole method (EDM) is first extended to analyze the scattering of chiral materials by solving the VIE. The co-polarized and cross-polarized bistatic radar cross-scattering (RCS) of normal chiral media, chiral metamaterials and chiral nihility materials are given, and the scattering properties of them are discussed.
