I'm currently try to setup some EM simulation that we have access to EM Pro. I want to set up a simulation that mimic the transmission tunnel of MAST technologies where there is a absorber in between two horn antennas. The insertion loss can be calculated from the S21.
Followed the horn antenna example I was able to simulate S11 of a single horn (and also the radiation pattern of it). However, I'm not sure what to do next.
P/S: I try to include two horn into the setup, but program stuck at the meshing process (I just did a mirror version of the first horn then add a waveguide port). I wonder if there is extra steps that I need to do?
