We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

回复老师:PCR是偏振转换效率,也就是右旋RCP入射时,出射光中左旋LCP所占总出射光的比例。按照几何相位的调制原理,也如我提供的式子所示,旋转角度Theta并不会影响LCP和RCP的幅度,只会影响LCP的相位,因此偏振转换效率应该不随Theta的改变而改变。与我的仿真不符合。

我尝试了把整个超原子区域,也就是FDTD区域设置成均匀网格,但是偏振转换效率还是随Theta的改变而改变。
