SubscriberI am trying to design a Circularly Polarization reflective metasurface. I want to know, how to get the accurate circularly polarized reflection parameters when I try to illuminate the unit cell with a circularly polarized excitation wave. I set one Floquet port having two modes, 90 degree out of phase from each other. After simulation, I am able to plot the (FloquetPort1:1,FloquetPort1:1); S(FloquetPort1:2,FloquetPort1:2); S(FloquetPort1:2,FloquetPort1:1); S(FloquetPort1:1,FloquetPort1:2); But they both seem to represent the linear polarizations. How to get the circular polarization, like S(RHCP,LHCP);S(LHCP,LHCP). Is there any formula to calculate it? Thank you.

Ansys EmployeeHi Caiweihong,
The mathematical expressions for transforming S matrix from linear polarization to circular is not part of HFSS. You may get the formula from some EM text books. On the other hand, you may revise your objectives and see how to use the HFSS report applicable to your objectives.
