摘　　要：基于Ｍａｘｗｅｌ方程组和电磁场的边界连续条件，本文导出了二元光学器件的严格的耦合波方程，指出各级次衍射波之间存在着相互耦合效应。用严格的耦合波衍射理论对二元位相光栅的衍射特性进行了分析，并与标量衍射理论分析的结果作了比较。Based on the Maxwell′s equation and boundary continuity of electromagnetic fields,this paper derives rigorous coupled wave equations of binary optical elements.It shows that coupling effects exist between every order diffractive wave.By using the rigorous coupled wave diffraction theory,the diffractive characteristics of the binary phase gratings are analyzed,and they are compared with the results of scalar diffraction theory.Some important conclusions are obtained.
