As part of a bigger project I am using a grounded CPW for a SIW in HFSS. I simply want to start with just making sure the CPW part works first before proceeding with the rest of the project so using a calculator I got the dimensions needed for a 50Ω characteristic impedance and proceeded to create my design. The issue that has me stumped involves the wave ports. I found the recommended dimensions for the rectangle but it throws an error for the wave port not being backed by a pec. I tried making my ports into thickened rectangles and assigned the excitations only to the faces facing into the waveguide and got no errors however looking at my S parameters I could tell I was not getting the correct results. Does anybody have any advice as how to fix this issue?
I am running modal simulations, the conductor is copper. I can provide any additional details as needed to find the solution.
