## HFSS simulation of metamaterial patch antenna

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

## how to vary angle of incidence of a plane wave in hfss?

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

## How to combine metamaterial design and patch antenna in CST?

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 (...)

## Simulate Unit cell of metamaterial structure

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

## HFSS Metamaterial Near-Field Simulation

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

## FEKO: S parameters extraction for metamaterial structure

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?

## EM simulation software recommendation needed

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
