Hi Qiuxiang,

You can use an analysis group called 'grating_s_params" to calculate the phase of the grating order. But I believe it only works for one target grating order at a time. You may refer to this article for more information: Metamaterial S parameter extraction. I am not sure if there is a simpler alternative, but I will let you know if I find something.

Is it possible to obtain its electric field through a monitor, and then set the angle of the corresponding plane to obtain the corresponding phase distribution?

I am not sure if I understood this correctly. Would you be able to tell me which plane are you referring t when you say "set the angle of the corresponding plane to obtain the corresponding phase distribution".

I would also like to point out that this channel (Ansys Optics) is meant for Zemax and Speos users. For Lumerical related questions, please feel free to post in Ansys Photonics Channel.
