| 摘 要： | 基于Maxwell方程的一阶状态矢量微分方程描述，从基本的差分原理出发，利用矩阵运算的特点，该文导出了各向异性材料中的时域有限差分（FDTD）迭代公式。通过对各向同性介质球雷达散射截面（RCS）的计算，验证了本算法的正确性。在此基础上计算了各向异性材料涂覆立方体的RCS，得到了一些有益的结论。

| Abstract: | Base on the Maxwell equation and the fundamental theory of the FDTD method and matrix operation, the FDTD equations about the electromagnetic field in anisotropic media are obtained. Some results validate feasibility of this algorithm. The FDTD method is employed to calculated the RCS of a conducting cube coated anisotropic media and some valuable conclusion are pointed out. |
