Hi knight87,
I don't use CST, but you want something like "Master-Slave" boundaries alone the transverse directions, and an absorbing boundary on the opposite side from the floquet port.
Good Luck

Hi PlanarMetamaterials ,
Thank you for your answer and suggestion. I will try it.

Hi, i am trying to create this structure, but i didn't. Someone can help me? How can i create this structure? when i create a box with a relative permittivity of 2.25, CST says : "Mesh is too dense or calculation domain may have zero volume".
