Handon Um

Hello, Amrita.

I missed one thing in my test.

The size of the pyramid structure in my latest reply is 0.5 um while the size of the first pyramid that occurs a large gap in the result of RCWA is 5 um.

When the pyramid size increases, it starts to show a difference between the FDTD and RCWA.


I think the thing is that an increase in the pyramid size requires a lot of resources to get accurate results.


I sincerely apologize for my mistake.
