I am trying to simulate an SRR unit cell in cst but I have some certain problems. can anyone help?
1) what boundary conditions I may use?
2) how I can simulate SRR's excitation? It is excited through an incident TE-pol wave. I don't know how to create the wave-guide port. Do I have to design a waveguide and put the srr in it? Which mode do I have to excite then?
