I am new to HFSS simulation.I am simulating a CSRR on ground plane of patch. I have already extracted parameters of unit metamaterial cell using master -slave boundary and floquet ports.I dont know how to apply boundary conditions to the patch antenna integrated with the CSRR.should i use periodic boundary conditions for the patch antenna?.Kindly h
Hi MEGHA_UNNI, In the future, such questions may be more appropriately asked in the Electromagnetic Design and simulation forum, as this one is more oriented towards theory. On to your question: Since you're working with a metamaterial absorber, I assume you are simulating just a single unit cell. In this case, you would want to use a Floquet po
Hi, I have designed a single unit cell csrr metamaterial and microstrip patch antenna using CST. I don't know how to combine these two structures together and what port (waveguide/discrete) should I used to run the simulation when they are combined. The boundary condition for metamaterial is magnetic for z axis, electric for x axis and open (...)
hii all, i am just start studying metamaterials so i have alot of problems>firstly,i am using HFSS program to design mtm unit cell and the first problem appers that i do not now how to excite this cell to calculate "S" parameter of the design...then if any one could help me to do this. how can i use these results in calculating epsilon and mu of th
hi everybody i design a MTM unit cell in HFSS like that. the wave port that i assign is true?C:\Users\mohammad\Desktop\1Untitled.gif111946 i use pec/pmc boundary
hi all, could any one give me some simulation of any ind of metamaterial in cst? i didn't get anything from Google. but i need to see how can i simulate a cst file which works on meta-material and an-isotropic.
dear I want to redo this article; "Suppression of the Mutual Coupling between Microstrip Antenna Arrays Using Negative Permeability metamaterial on LTCC Substrate" i do the simulation but in S21 i can not get the result of paper's simulation so i add the 16 SRR but i can not get the result please help me 106863 106
Hi everyone. Normally, when simulating unit cell SRR of metamaterial structure which is excited by H-field, we often put 2 wave ports and H-boundary parallel to SRR-Plane, E-boundary normal to SRR. is that right? I wonder there is other ways? Is this possible to use Floquet Port for Unit cell simulation? How can I do it? Many thanks
Hi, everybody. I am working for a project about Wireless Power Transfer using Magnetic resonance. This field is quite new to me. I use HFSS simulation for this. I have two resonance loops with the same resonant frequency and two metamaterial blocks as repeaters. Resonant frequency is 13.56MHz. Diameter of loop is about 200mm (From previous pape
Hallo every one, I am a beginer to HFSS as well as antennas , I have chosen my area of research as metamaterial based planar antenna for which ,i have collected many papers , i have gone through them . My need is if any one can help me in giving tutorial for simulation of such it is very urgent.Thank you in advance.if. any one can su
i simulate a SRR unit cell in HFSS but when I change the height of the radiation box ,result have change so what should be the height of the box .Please help me ,it is very urgent.
I need an example project with setup (antenna with metamaterials (HFSS ;CST) ) and what should be the height of radiation box while simulate in HFSS
what is a difference between dispersion diagram which get from eigenmode solver in cst and other ways such az manipulation whit ABCD parameters? how i can simulate one unitcell of a metamaterial structure inorder to obtain dispersion diagram : it means i should ommite other unitcell and i do the simulation just for a unitcell?!!!8-O 8-O :!:
Any one able to correct this setup of metamaterial unit cell with periodic boundary condition and floquet port. What should be the size of the airbox. And what should be the orientation of unit cell. And What should be the criteria to choose the scan angles for phi and theta. And How we can run metamaterial unit cell with periodic boundary simulati
I want to extract the LCRG parameters of a structure based on a method established by S.Otto & Al. in this article "An Energy-based Circuit Parameter Extraction Method for CRLH Leaky Wave Antennas". In simulation, i've used PMC wall (Perfect H), periodic boundaries (Master & Slave) and PML box. My first objective is to get the shunt and the seri
std. FR4 is too lossy > 500MHz so consider low loss polyamide FR4 like GETEK. Consider fractal design of conductors.
Try to read some papers of Y. Samii and Sievenpiper. You can design a mushroom type EBG materials for metamaterial and use it with patch antenna.
Hello!! I'm trying to simulate a metamaterial srtucture in HFSS, the problem is that when i change the size of the vaccuun box, the S-parameters change too, which causes a switch on the ressonance frequency, i read the topic about the size of the air box, but i still couldn't figure out what's wrong with my setup, i add the file of my simulation
hi, I'm working on metamaterial structures. In HFSS, I'm using PCB (Periodic Boundary Condition) (Using Master-Slave) for simulation. my problem is that i haven't any Phase in the S11 and S21. what i have to do? thanks for your help....
Hi friends Does anyone has a project in HFSS about split ring structure? I am trying to redo the project of M.Z.M.Zani, M.H.Jusoh,...'''Circular patch antenna on metamaterial'. If anyone help me to do this, I would be very grateful.
