Abstract

The regularization of the well-known recursive T-Matrix method for 2D monochromatic wave scattering problem from multiple circular dielectric cylinder system is elaborated. It is the numerical stabilization of the recursive T-matrix method composed in terms of isolated T-matrices of each scatterer. Numerical results show that it is much safer to proceed with the regularized recurrence operations to get accurate results computer precision can provide by ensuring the reliability of the solution.
圆边界TM-z散射二维递推T矩阵法的数值稳定性
阐述了求解多介质圆柱系统二维单色波散射问题的正则化递归t矩阵方法。它是由每个散射体的孤立t矩阵组成的递归t矩阵法的数值稳定性。数值结果表明,在保证解的可靠性的前提下,采用正则化递归运算来得到计算机精度所能提供的精确结果是更为安全的。
