摘要
本文讨论了用T矩阵求解散射场时,散射场展开项截断系数n取值的问题。取值的原则是既要保证T矩阵方法的计算精度也要保证计算的收敛性。
In this paper, we will discuss the value of the truncation index N in the extended repressions of the scattered field when we solve the scattered field by T-matrix. The principle which will decide the value of the truncation index N not only insures the computing precision for T-matrix method but also ensures the computing convergence.
