      I have simulated the unit cell of a metalens. I have used two plane wave to simulate the circle polarization. I wanna know how to get the cross-polarization efficiency and phase in FDTD

      the result with the S in sweep is not correct.

      I just found your post which is in the wrong forum. Lumerical has dedicated English, Chinese and Korean forums:

      Next time please post in the proper forum in order to get quick reply.

       

      Do you have math definitions for  cross-polarization efficiency and phase? I guess you will need to get the expression of the "cross-polarization" then can use calculate them.
