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 (...)

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

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 jillu i suggested u this paper "MICROSTRIP ANTENNA'S GAIN ENHANCEMENT US-ING LEFT-HANDED metamaterial STRUCTURE" by H. A. Majid, M. K. A. Rahim, and T. Masri in Progress In Electromagnetics Research M, Vol. 8, 235-247, 2009
Forgot to add, first characterize your metamaterial and get the 'dispersion diagram' and identify your 'bandgap'. This bandgap will stay the same,for it near-fiel/far-field thing is irrelative. The next step then would be to put antenna on top of it and see the effect. The high-impedance surface will act as a perfect reflector only in the 'band-ga

Can anyone give me some knowledage or tutorial on how to simulate metamaterial on FuLLwave software by Rsoft. how to set PML, PEC and PMC
hi guys, I am using cst to simulate metamaterial sturctures. One problem confuses me a lot : I oftern got results of s11 and s12, which do not satisfy law of energy conservation, since s11^2+ s12^2 >1, even in the case of lossy metal structure. I thought something is wrong with my simulation . To my surprise, many cst official modals also gen
Hi all Can anybody help me with simulating metamaterials with FDTD Codes? thanks
I am very interested in this topic. I am working on this now. there some information about MMT in FEKO on the FEKO website , dont know if you know about it: and
In metamaterial simulation, CST and HFSS are widely used. I don't know people using FEKO to simulate metamaterials. But I think in principle it works too. By NO ports, do you mean you just computed the problem as scattering? Then you got the scattered field, from which you want to obtain conventional S-parameters?
Hello. Now, I try to simulate ring resonator metamaterial for THz region using CST. I got a similar simulation result like reported in PHYSICAL REVIEW B 75, 041102 (2007). But, I wonder my result is correct: mesh size and other conditions. I attacehd my simualation file and papaer. Some CST and/or metamaterial guys give me (...)

Oxford, UK, September 4, 2008 --- Vect
i have little experience on CST, more on HFSS. your choice should depend on the type of metamaterial unit cells you are using. as far as I know and remember, CST is using rectangular grids and subgriding. It becomes a little bit difficult for rounded geometries to use these types of rectangular grids. and, from my experinece, adaptive gridding w

Hello! I am totally newcomer with HFSS and what I want to do is to simulate a simple metamaterial unit cell structure in HFSS. The structure dimensions, boundary conditions and the structure itself are from Kevin Buell, Hossein Mosallaei and Kamal Sarabandi - "A Substrate for Small Patch Antennas Providing Tunable Miniaturization Factors" IEEE a
I don't think Jin A. Kong would run the simulation himself. Even if he does so, that doesn't mean CST is "Good Enough". These professors might know a lot about metamaterial, but...

Thanks everyone I need a help on the topic of simulation of metamaterial. Who can tell me which software, or any codes, or any method is avaible?
I was trying to redo a simulation that I read in a article. It is about measuring permeability of a metamaterial. I have finished the model same as the sample D1 described in the article using HFSS 10. But I don't know how to set up the excitation and boundary, and how to measure the permeability. Specifically, I want to create a graph of the imagn
Hi all, Has anybody simulated a simple metamaterial structure that exhibits negative ε and a negative ? in CST or HFSS ? I just am curious to see how stacking wires and SRRs closely provides this effect. It is purely for academic interest. Anyone who has done this type of simulation, can you share a simple model with me ? -svaru
