Dear Sir, I 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.
Very good and useful explanation sir. Many thanks
Kindly make a video for plotting attenuation with respect to frequency and plotting axial ratio from e and h value

Tau first attempt and classic second attempt both failed ? What should I do
There is no floquet option after assigning boundary ?can I know what is the reason?
Go to HFSS option in top panel-> Select Solution Type -> Change terminal to "Model" click OK. Try Floquet port.
Solution type must be modal.
