## HFSS Floquet Port circular polarization

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 (...)

## [moved] please want help HFSS Floquet port unit cell

Hi sztr, You need to do pretty much what hfss is telling you to do: ensure that the floquet port is touching orthogonal Master/Slave boundaries. There are some good tutorials included with hfss that explain how to use floquet ports.

## Floquet port - How is works and captures waves ? Simulation queries

Hi , I am a beginner w.r.t hfss and i want to use it for a whole new purpose. i.e for simulating solar cells. I am interesting in how light is interacting and getting reflected (absorbed) at different layers of my solar cells. (i have some periodic structures) To begin with, i modeled a simple solar cell : 1) Setup a 3 layer solar cell (glas

## S21 Floquet port in HFSS

Hi everyone I've got a basical doubt in the way floquetports are numerated in hfss. My doubt is as follows: If I plot S(floquetport1:1,floquetport2:1). Am I plotting the S21 parameter of the TE mode or the S12 one??. I know that if you have a symmetric matrix that topic (...)

## Can we calculate RCS of an FSS structure using Floquet port

Hi to all; My question is that, Can we calculate the RCS of an FSS design in hfss by using the floquet port? I have been told by some one that you should use incident plan wave to excite the unit cell of FSS and for that also change the solution setup in hfss. Is there any way to calculate the RCS using (...)

## problem in finite FSS simulating use HFSS

In a infinite structure we know we can set BC as master & slave and floquet port to analysis, but when I want to analysis a 5*5 structure How should I set the BC and what port can we use?

## HFSS FSS polarization simulation

If your unit cell is either rectangular or square, then by solving for the first two modes (orthogonal polarizations), assuming you need no more than that, in the floquet port you know all you need to know about the polarization dependence of a structure at a given angle of incidence. If your structure symmetry is aligned with the modal excitation

## Metamaterial unit cell simulation with Floquet Port and periodic boundary condition

Hi sc4rppph, As a disclaimer, I don't use floquet ports, but the setup looks correct to me as far as I know (hfss 13). For the master/slave boundaries, you probably just want to use the specified phase angle rather than theta/phi for square structures. To get the dispersion diagram, set the phase angle of Slave X to a variable AngleX and (...)
