  您好，各位老师同学，想问一下，我仿真的是超透镜的单元结构，我调试了好多数据，左旋转右旋的转换效率和右旋转左旋的效率总是不重合，我不知道是否两个转换效率是否必须一样？

  由于偏振效应，一般情况下它们是不同的，除非你的单元设计保证它们一样。

  您好，请问其中包含了什么知识点嘛？我刚接触圆偏振光，查了好多资料没有相关解释，您说的偏振效应是指什么意思呢？

  偏振问题是一般教科书最薄弱的环节，一般人对偏振的了解还比较少，这个也很正常。
  
  偏振效应是指，斜入射的平面波P和S光的反射率透射率不等，在一些微纳器件中，即使正入射，某个偏振可能大部分被反射，而另一种偏振可能大部分投射。你看一下这个例子
