| 摘 要： | 分析了二维无限长均匀各向异性椭圆柱体的电磁散射特性。基于平面波谱的积分方程以及马丢函数的级数展开式，以横电型(TE)平面波为例，导出了均匀各向异性椭圆柱内场及其单位长度的雷达散射截面(RCS)的表达式。计算了部分数值并讨论了电尺寸、介电材料等影响雷达散射截面的因素。当椭圆柱体退化到各向异性圆柱时，数值与已有文献的结果吻合较好。

| Abstract: | An analytical solution to the problem of two-dimensional scattering by a homogeneous anisotropic elliptic cylinder is derived.With the aid of an integral equation based on a plane wave representation of the field and the series expansions in terms of Mathieu functions,the transmitted field of the elliptic cylinder and radar cross sections per unit length under a transverse-electric illumination are obtained.Some numerical results are presented,the effect of electric size and material of elliptic cylinders o... |
