      Somehow this post was left unreplied. Please post in the English forum since this is a Korean forum.

      Sorry I am not sure what the device you are simulating. Does the incident source have any angle? is there any wedge element inside the device? do you use any periodic boundaty conditions?

      Please try to use a linear polarized light and check if the result is normal.
