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
hello, please explain about how to simulate this floquet modes in hfss with more details. for example how to define or specify angle of incident to any of element ?
hello guys. i try to simulate reflectarray antenna element with t-shaped patch.i work with hfss and i use master and slave boubdary and floquet port for my periodic how can i excite my patch in x or y direction with floquet port??? and how can i see co-polarization and cross polarization from (...)
Hi I am a new user of Ansys hfss. I am currently having some floquet port difficulties for my design. I have done the tutorial for floquet ports that is available in the learning guide. However, when I try to assign the floquet port at one of the faces this error message (...)
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. Now i need to test it by exciting the antenna using floquet port. So i put master and slave conditions floquet port and then what ? how to proceed after what are the (...)
I am modeling a periodic structure with a floquet port in hfss. I have a tall rectangular box whose top face is a floquet port and bottom is PEC. a unit cell of teh peridodic structure is within the box. I have master and slave moundaries on the side walls. I would like to simulate a scattered field (...)
Hi all, I am now modelling a reflectarray cell element in hfss, but come across a problem when setting the floquet excitation. I have drawn an airbox, four sides of it are assigned with Master/Slave boundaries and the bottom side left with empty and align with the ground of the cell element. The top side is set as 60mm away from the upper rectan
I'm trying to design a planar phased array antenna consisting of circular dielectric waveguide for 15.25GHz applications(lattice is skew). i modeled hexagonal unit cell in hfss with master/slave boundary condition and PML. and then i want to see my anten impedance matching in all scan angle is good or no!! floquet port and PML toghether (...)
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. (...)
any one can upload hfss or CST file of reflectarray please
i am doing my project in rcs reduction of frequency selctive surfaces.. i am using hfss 13 for simulation i selected a unit cell and upo validating i gt an error as hfssDesign1 (DrivenModal) port 'floquetport1': The exterior boundary of the faces for a floquet (...)
hi,all i'm trying simulate periodic structure in Collin's book " foundations for microwave engineering" chapter 8 page 552 ( capacitively loading of coaxial line),by hfss, I want define Master and Slave and floquet port, but i don't know how consider master and floquet? i will be great full if any suggest.
Hi, I am using hfss for the Unitcell, I wants to find S21 as function of frequency for different incident angles in floquet port. please anyone could suggest me how to change the incident angle of plane wave in floquet port.
Hi everyone, My model have one floquet port with TE and TM mode. When I finish work and see S parameter, it's easy to understand s(floquetport1:1,floquetport1:1) and s(floquetport1:2,floquetport1:2). but what (...)
