摘要
根据麦克斯韦基本方程组 ,推导了描述任意槽形光栅衍射特性的矢量理论分析方法——严格的耦合波方法 ,该方法可用来分析具有任意面型函数光栅在 TE ,TM两种偏振模式的平面波入射下的光栅衍射特性。
Based on the Maxwell equation and the boundary continuity of electromagnetic field ,the vector theory analysis method-the rigorous coupled wave analysis technique for describing the diffraction of electromagnetic waves by any shape profile gratings for both TE and TM polarization is presented. For any shape profile gratings ,the distribution of diffraction efficiency with TE and TM polarization are given.The effect of grating structure parameters, incident angle and polarization on field is investigated.
