摘要
基于麦克斯韦方程组和电磁场的边界连续条件，本文导出了位相光栅的严格的矢量耦合波衍射方程，指出了各级次衍射波之间存在相互耦合作用。并分析了光栅的偏振效应，得到光栅在不同偏振方式下的衍射特性。
Based on the Maxwell′s equations and boundary continuity of electromagnetic fields, rigorous vector coupled wave equations of phase gratings are derived. It shows that coupling effects exist between every order diffractive wave. The polarization properties of gratings are analyzed when different polarized fields are incident. Experimantal results verified the theoretical analysis.
