Hi...
I did fss in HFSS ver.12.
My steps in HFSS are as follow
1) Draw a unit cell
2) Draw a air box
3) Assign PML to top and bottom face (and add fss reference on top face)
4) add master and slave boundary
5) add excitation: incident wave which is plane wave

After I run, I plotted for magnitude and phase of S11. However, my phase is all zero. I got only magnitude of it. So, somebody here know how to get phase for S11 or what did I do wrong in HFSS?

Thank you very much
 

Use Floquet Ports. They specifically solve in terms of S parameters and one can easily retrieve the phase and deembed to an interface easily. There is a tutorial on Floquet ports in the HFSS help.

Have Fun
