一种快速计算电磁各向异性介质目标RCS的新方法
Fast Calculation Method for RCS of Electromagnetic Anisotropic Dielectric
摘要
Abstract
Volume integral equation (VIE) for electromagnetic scattering of anisotropic dielectric is derived according to the volume equivalence principle. Schaubert-Wilton-Glisson (SWG) basis functions and Garlekin method are applied to build matrix equations. Both the equivalent dipole-momenf. method (EDM) for fast filling impedance matrix elements and the fast dipole method (FDM) for accelerating the iterative solution by expediting the matrix-vector products (MVPs) are employed to reduce the computing time compared with the conventional method of moments (MoM). Furthermore, in FDM, the matrix elements among the far groups are implicit calculations and the simple aggregation, translation and disaggregation functions are performed directly when they are used, which save memory significantly. The numerical results show that the new method has high efficiency and low memory requirements, as well as good numerical accuracy.关键词
