I would like to know how to plot the propagation constant in a typical microstrip structure, as shown in the image.

The goal is to determine the propagation constant of the surface wave generated under specific permittivity and substrate height conditions.

I have seen tutorials on YouTube explaining how to plot the propagation constant in waveguides, but I am unsure how to configure the ports and boundaries for a microstrip structure.

 

For reference, I have set up the HFSS configuration as shown in the image.

How can I plot the propagation constant of the surface wave ?

For the plot see the video at about 2min:30sec - 3min:30sec  in the video:

As for the BC perhaps some forum members can chime in here:

Perhaps the below helps:
