      老师,第一幅图是我用左旋光做的仿真图,第二幅图是我用右旋光做的仿真图,但是和我论文中的结果图不符(论文当中的幅值,在左旋和右旋光条件下应该是保持一致的),后来我对脚本做了修改,我把右旋光的代码中电场的表述式改为了Ey+iEx,再求Abs结果就对了。

      我的问题是,为什么Abs会对Ex+iEy和Ey+iEx的计算出来的结果不一样呢?

      当你使用Ex+-jEy形成圆偏光时,你事实上已经假设abs(Ex)==abs(Ey)。

      Ex+iEy和Ey+iEx 是两个相反的偏振光啊,Ey+iEx=j(Ex-jEy)与Ex+iEy选项相反。

      所以,这里面还有不少理论问题需要琢磨。

      那么既然是左旋和右旋是相反的圆偏振光,那么我计算的幅度谱,不论左旋还是右旋,都得按照Ex+iEy来算才对呢?因为如果我左旋是Ex+iEy右旋是Ey+iEx,那么右旋不就也成了左旋。
