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
Welcome Vittal Rao, floquet ports need to be used in conjunction with master-slave boundaries. There is a good tutorial of this in the hfss help. Good Luck!
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 (...)
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 (...)
in the design, if air box be from -5 to 5, how much de-embed we need? and what happens for S11? its good or not? how it should be? and in the design you define variable of "a". for what?

Hi, Anyone knows about how to check the angle variations in case of Frequency Selective Surface using the wave-port in hfss. Actually i want to verify the results of FSS unit cell using floquet port and wave-port in hfss. Please guide me how the task could be done. With Best (...)
hi , i am trying to simulate microstrip reflectarray with hfss. I have used two master slave boundary condition and one floquet port excitation. Then in the parametric study i have varied the size of the patch but not able to generate the S curve of phase vs patch size. So please help me in this regard. Thanks
Anybody knows valid excitation ports for using the finite array tool of hfss? It gave me an error when I used floquet ports which makes sense. But I can't use wave port either as there are master/slave BC.
Hi I want to simulate an array antenna and measure its reflectance & transmittance So I build unit cell of my structure and define its bottom sheet as waveport. Then master/slave for its side boundary conditions is defined. At last floquet port is set to its up unit cell's sheet. After simulation, in S-parameters I couldn't find any resul
Dear all, I am new in using hfss, and I need to simulate an infinite array of circular waveguide disposed on an hexagonal lattice, working at 15.25 . The radiating elements are covered by a layer of an anisotropic material. Such a test case is reported in the paper: S. Sajuygbe et al. "Wide angle impedance matching metamaterials f
Hi to all; I am using the floquet-port with master-slave boundaries but the confusion that i am facing is how to check angle of incident wave at the floquet port. While i follow this procedure Slave->Phase-delay-> phi & theta and have change the values in the phase-delay in slave boundaries where i use phi (Φ) as (...)
Can any one tell me that how much deembed distance for floquet port in hfss should be kept for good simulation results in hfss. Is there any rule for this distance or on hit and trial base. :grin:

Hello all Am simulating a circularly polarized frequency selective surface using hfss floquet port model In a unit cell configuration. In order to achieve circular polarization, i have defined port one wave one to 1W, 0 deg Phase, and port one wave two to 1W,90 deg phase. After running the model, how (...)
A guide to floquet port in hfss v11
This tutorials explains how to do that.
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? Because I need to create a TEM wave, and when we use radiation BC and wave port can't create a TEM wave. So hope someone can help with (...)
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
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 (...)
Hi, I am a new user of hfss and also a newer of electromagnetic theory. I want to simulate a periodic model using floquet port (with normal incidence). When I configured the excitation parameters of floquet port (in the Tab floquet port -> Modes Setup ), I found that (...)
are u getting errors or results are weird? if that is copper u will have currents flowing around the boundary... The error is boundary overlapping error when performing validation check. Results are not weird for this case, as I am looking for S parameters only (reflection and transmission), but still a little diffe

I am trying to follow hfss tutorial on floquet port but i am getting following error messageFailed to solve the problem due to lack of precision. The likely cause is that the frequency is too low..I have attached the tutorial and hfss file both.Any help will be greatly valuable to solve this error. Thanks
Hi i am working on a unit cell of a reflectarray patch antenna with slot coupled to a microstrip. I tested the antenna with a micro strip excitation.

Hi, I'm trying to excite a floquet port with a circular polarized wave, but I can't find the way. What I'm doing instead is calculating the results by calculating the fields for the floquet modes 1 and 2 [S(floquet1:1,floquet1:1) and so on... My goal is to mesure the axial ratio and the S parameters. (...)
Hi guys, I am trying to simulate one unit cell of the reflectarray element in hfss, to get the phase-size curve. My question is: when I put a waveguide port or floquet port above the patch, what kind of deemed distance should I use? Should be deemed at the patch surface or at the ground surface? I think it should be (...)

Hi everybody!!! I have been researching reflectarray antenna recently, but I encounter some problem :sad::sad: to be quite honest, I start to use hfss for a short time, so I can't grasp the way using it perfectly.

This was a real problem for my when I was working on my thesis, but finally I found the answer. How much distance for floquet port in hfss? Well, the answer to this question is rather complicated. Yet the distance could be obtained easily for each structure, frequency, and incident angle. As you know when a periodic surface is (...)
i don't want use the Master-Slaver BC and floquet port to solve the problem, which recommended by hfss hand book. i have draw a 8*8 (finite-unit) FSS in hfss 11, and just care about the 4*4 units in the central area. How should i set the boundary condition and Excitation?
simulating a FSS unit with floquet port, when setting floquet port ,post processing, deembed distance how can i set the value of deembed distance need your help ,and thank you
You can't. hfss does not give you this information nor allow you to specify what modes to be input to the port.
