大纵横比物体电磁散射问题的推广T矩阵程式(英文)

Formulation for Large Aspect Ratios Scattering Problems with Elliptic Cylindrical Wave Functions

由于原始的Ｔ矩阵不适用于求解具有大纵横比物体的电磁散射问题，针对二维问题，通过对其格林函数的椭圆柱波函数展开，提出一种求解二维电磁散射问题椭圆柱波函数的Ｔ矩阵程式（推广Ｔ矩阵）。结果表明：推广Ｔ矩阵能够很好地用于处理谐振频域的大纵横比物体的电磁散射问题。

In this paper, a developed T-matrix method (Extended T-Matrix Method) based on elliptic cylindrical wave function is proposed for two-dimensional scattering problems. Computation results show that the method is well applied in large aspect ratio scattering problems.
