Axial Ratio in HFSS for square waveguide septum polarizer

Dear friends,

I have modeled a steped septum square waveguide polarizer, which makes two linear pol to a RHCP or LFCP and vice versa.

I have find all the S Parameters very good.

But I need to see the axial ratio between the two orthogonal components Ex and Ey.

Please explain me how can I plot the axial ratio of the CP in waveguides.


Best regards

Hi.
I'm working on same thing on 10.4 GHz.

Your question contains very little information.

Frequency? Supplying? Model definitions?...

You need define "radiation boundary" in Boundary menu and "infinite sphere" in far field in Radiation menu, than you can plot calculated axial ratios.

If you want more comments, upload your HFSS project here or send me a PM.
