摘要
从时域有限差分法基本的原理出发 ,利用矩阵运算的特点 ,推导出了电各向异性、磁各向异性以及导电率各向异性的材料中的FDTD方程。验证了算法 ,并计算了各种单轴和双轴各向异性材料的雷达散射截面RCS ,讨论了各向异性材料的散射特性。
Based On the fundamental theorm of the Finite-Difference Time-Domain method and matrix operation,the FDTD equations about the electromagnetic fields in anisotropic media including electric anisotropy and magnetic anisotropy and conductive anisotropy are obtained.Some results validate feasibility of this algorithm,radar cross section (RCS) are presented to discuss scattering of 1 anisotropic scatters.
