In this talk, the operator marching method for the scattering problems of nano-periodic structures is introduced. The scattered fields are fast calculated with high accuracy. Then, the surface integral equation method for analyzing the scattered electromagnetic fields on diffraction grating structures will be presented. Next, we propose the numerical steepest descent path method for solving the high frequency scattered fields. Numerical results on the electrically large scatterer models illustrate that the proposed method is frequency independent in computational cost and error controllable in accuracy. 报告人简介：2008年获中国科技大学博士学位，2009-2010年香港大学博士后研究员、2010-2013年美国伊利诺艾大学计算电磁实验室研究员。2013年全职到复旦大学任引进副研究员。研究方向为复杂目标的计算电磁学研究。
