how I can check if floquet ports are correctly oriented in the same direction in CST

[sztr]

Hello everybody ;
I wish to have help please; analyzing the phase of the output S21 of my structure floquet ports under CST I obtained an opposite phase to that I obtained by modeling; the same phase, but reversed (multiplied * (- 1)); I think the error is in the direction of polarization of the ports but I do not know how to access their configurations under CST knowing that in HFSS we hand to do
thank you
