Ansys Employee我这边测试没有问题,很可能是哪里设置有问题。你这个只需要设置一个min(起始),两个max(两个界面,光栅与基底,光栅与空气)即可。
如果还有问题,你需要将结构拷贝到全新的RCWA Project 文件,再测试。
或者重新启动计算机;
或者重新安装最新版。

Subscriber感谢老师解答,请问能用RCWA来计算光栅的衍射效率吗?因为我看有些例子是用FDTD仿真区域来实现的。如果能用RCWA来仿真,那么请问上述的RCWA的仿真区域建立正确吗?

Subscriber我将2D的RCWA改成3D之后,就能正常运行,难道是光栅的衍射效率仿真必须得用3D吗

Subscriber老师,如果是二维光栅的话就要用3D,如果是一维光栅,就用2D仿真,这样理解对吗?其次,光栅的某一阶的衍射效率是在grating order里面查看?

Ansys Employee对。
在Total Energy里面,衍射角作为变量,当波长一定的情况下。

Subscriber但是Total Energy里面,观察到的不是总的衍射效率吗?我需要看的是在某个偏振下,具体某一阶(例如+1阶)的衍射效率,请问在哪看?

Ansys Employee你先将T提出来看看矩阵的维数。
目前这种数据格式不那么直观。但是RT是波长/频率,Theta/Phil的函数。前面已经给你说明了,你需要提取出来看看。

Subscriber另外,请问老师,Surface Relief Grating for Augmented Reality System这个例子能正常运行吗?

Ansys Employee相反没有关系。
那个例子鞥运行,但是可能不能完全重复,有问题请另外发帖。
