Hello.
When I run a simulation for a simple rectangular waveguide in a frequency range that includes the cutoff frequency, I should see a change in the S-parameters that show the cutoff behavior of the wave stream. But S11 does not show what should come out according to calculations.The cutoff frequency should be at 6.5-13 GHz. The waveguide itself is 23x10 mm length 1000, wall width 1 mm.According to calculations here only TE10. I use Time Domain Solver. Boundary Add Space.
