中文摘要：
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.
英文摘要：
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 on the radar cross sections is discussed.The data are in agreement with those available as expected when the elliptic cylinder degenerates to a homogeneous anisotropic circular one.
