-
摘要: 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。Abstract: 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.
