How to set the boundary conditions of the beam envelope

Please login with a confirmed email address before reporting spam

Hello

I simulate a metalen model when a circular polarized light is normal incident. Because the minimum eigenvalue is smaller than the wavelength, can I use beam envelopes for simulation? If so, how should the boundary conditions of the three-dimensional structure be set?

I put the structure diagram in the attachment

Any help will be appreciated. Thank you.!
