Hello,
I'm new to COMSOL. And I have a question about the boundary condition of RF module. Hope someone can give me some suggestions.
I'm using COMSOL RF module to simulate the transmission of a 3D irregular gold film with different incident angles as attached picture 1. Because the surface and edge of gold film is irregular and asymmetric, so I'm wondering what boundary condition should I use in this case. Floquet periodic condition can not be work because the gold film is not asymmetric and it will have problem in meshing.
I also have tried the PML as attached picture 2. But the result is totally incorrect(as attached picture 3) because the transmission should not be more than 1 in this case.
To summarize, my question is what boundary condition should I use to simulate the transmission of a irregular gold film with different incident angles?
Hope someone can give me some suggestions. Any reply will be helpful for me.
Thanks.
