Time varying Impedance in HFSS

  Hello, I have an incident beam launched at an antenna that I want to load with a certain impedance that should switch between two values periodically. Is there a way to achieve this? I was thinking about utilizing co-simulation with Circuit, but did not get far.
  
  Thank you in advance!

  If you are ok using resistive termination as the load here, you can make this work in Circuit by driving a voltage controlled resistor with a pulse source.

  Thank you for the answer. Could you please provide more detail on how to setup the link between HFSS and Circuit? Ideally, I would want to have a sheet in HFSS and assign an impedance boundary. The value of this impedance boundary should be switched.
