Hello I am learning how to use HFSS and am trying to replicate a metasurface. The metasurface is designed for circular polarization so I am using floquet ports to simulate a unit cell. I turned on TE mode and also TM mode but with 90 degree phase in edit sources so that it would create a circularly polarized mode. Where I am having trouble is how to setup the second floquet port to read the s parameters for the circularly polarized mode?



 

Welcome quetranza,

I haven't done this before, but I believe you'd have to create your own S-parameter curve definition in the HFSS report. It's probably also best to de-embed both ports to the surface, such that you don't have to worry about phasing issues.
