老师,我可能问的有问题,我是做超表面的仿真。现在有一束圆偏振光垂直入射到超表面上,然后反射。那入射光和反射光的琼斯矢量关系应该是Er=JEi,J应该是个2X2的矩阵,四个参数分别为J11 J12 J21 J22,老师,我现在的目的就是想通过仿真求出这四个参数。  我的想法是,把Ei分解为X分量和Y分量分别入射如【1,i】=【1,0】+【0,i】。首先是【1,0】入射仿真会得到一个反射光【Exr1,Eyr1】,首先用abs提取Exr1和Exr2振幅并归一化设为x分量为a,y分量为b;再用angle提取Exr1和Exr2 的相位,并计算相位差为φ ,整理完的琼斯矢量为【a,b*exp(iφ)】那也对应着J11和J21   所以J11=a  J21=b*exp(iφ),然后【0,i】那个同理,最后算出J12和J22。请问老师我这么做对吗,我看的论文有很多关于琼斯矩阵的,但是在论坛没有找到过相关的帖子,谢谢老师!
