CST Studio Suite I am trying to simulate the characterization of a slot waveguide using an infinite array approach, with the geometry as shown in the figure. I set the X-plane boundaries as periodic and the Y-plane boundaries as periodic as well, but with a 180-degree phase shift. The top side of the Z-plane is set to Open, and the bottom side is set to Electric.
Then, at the beginning and end of the waveguide, I added waveguide ports.
I am using the Frequency solver to observe the S-Parameters. However, the simulation returns an error:
"Waveguide port 1 is defined on a periodic boundary. Waveguide port 2 is defined on a periodic boundary."
How can I resolve this error?
