I really need help with the Master/Slave Boundary in HFSS.
I want to simulate SRR array using Master/Slave Boundary. I don't know how to set up the phase delay. I just want to simulate TEM wave normal to the structure and see S21 parameter. Should I set phi and theta to zero?
If the wave is at normal incidence, there is no phase difference between your boundaries. That only happens when the wave is at some oblique angle of incidence. In this regard, normal incidence is extremely easy with HFSS.
