摘要
本文针对普通数值方法求解物理光学的时间慢或精度的缺陷,根据最近几年学者提出基于广义积分法求解广义高振荡Fourier型积分,提出了基于广义积分法则的物理光学(GQR-PO),通过电磁算例验证该方法,对于求解电大目标具有精度高,消耗时间短,内存消耗小等优秀特点准确性和高效性。
A general numerical method for solving PO integral has some shortcomings, such as low precision or more time-consuming. According to the theory of generalized integral rules developed, in this paper, a numerical method are proposed for PO integral, and some example is given to demonstrate the method that has high precision, short time consuming and low memory consumption for solving electrically large objects.
