hfss s(1:1, 2:2)
Hi,
I am looking at a simple rectangular waveguide and simulate in HFSS. I use waveport simulation for up to 3 modes from 1-20GHz. I think the number of modes are sufficient in this case. There are different combinations of S-parameters like S(waveport1:mode1,waveport2:mode1), S(1:2,2:2), S(1:2,2:3), etc.
How do you actually combine these S-parameters if you, for example, want to compare with network analyzer measurements? Should you just sum the square of all the S12, then do the same thing for S11, S21, S22.
I tried to do this for S12. I only sum the modes S(1:1,2:1), S(1:2,2:2) and S(1:3,2:3). But I started to get the results greater than 1 after the 2nd cutoff?
Any ideas? Thanks in advance.
