ABSTRACT Scattering 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.

普通手性、超材料手性和手性虚无材料的电磁散射分析

摘要介绍了普通手性材料、手性超材料、手性虚无材料对电磁平面波的散射。基于体积等效原理，积分方程用一对耦合的双各向同性极化体积电和磁通量密度表示。体积积分方程 (VIE) 使用矩量法 (MoM) 结合四面体网格求解。然后将自适应交叉逼近（ACA）算法与基于等效偶极子法（EDM）的快速偶极子法（FDM）相结合，首先通过求解VIE扩展到分析手性材料的散射。给出了普通手征介质、手征超材料和手征虚无材料的共极化和交叉极化双基地雷达交叉散射（RCS），
