Hello everyone,
I'm trying to simulate a single asymmetric cell of FSS structure. I'm using HFSS 10.0. It has no ground plane, so I need to look for the transmission S21 afterwardes.
1-I tried to use simple E-H planes with two wave ports. The results are not so bad, ut they are very sensitive...
hfss to compute effective permittivity
I'm using Microwave studio to compute the eigen-modes, and HFSS for the S-parameters.
MATLAB compute the parameters as mentioned in the paper I cited.
It soesn't matter if MATLAB or anyother program.
I compared the results with some published results and...
rcwa matlab code
In fact, I simulated one cell of the structure to find out all the eigen modes.
So, I know already how should I get the refractive index for infinite structure.
Then, I simulated different number of cells. Furthermore, I fabricated all of them and measured them as well.
The...
difference bruggemann maxwell garnett
Oh, that is very detailed answer.
In fact, my structures are rather simple. They are split ring resonators with rods coupled to transmission line. That's it.
I tried to implement the algorithm in this paper:
"Robust method to retrieve the constitutive...
In fact, I would like to draw dispersion curve for Split rinf resonator on the top of dielectric substrate.
I think I have to do that using Eigen mode analysis by changing the phase shift in some directions, isn't it ??
Yes, I agree. But this exactly what they mentioned. It is 400 um.
For the feeder: I think it should be no problem. I checked the input impedance and it is about 50 Ohm as they wrote in the paper.
So, it should be ok.
May be it is the effect of lens ?? I have no lens in my design, and they have...
momentum cpw
Thanks a lot.
I've got another question.
When I draw the phase results in rad., I can see the result between ±3.
My question: How I can draw between let say ±10 ??
So, to compensate for the phase response.
intern ports for cpw on cst
Sorry for my question. I'm very new in HFSS world.
If I have substrate and CPW on top without ground. Then, I learnt from the above tutorial the dimensions needed for this case.
My questions:
1-How can I define the wave port ? Shall I draw rectange and assign it...
comsol hfss
Hello,
I understood the opposite.
I understood that MW CST and HFSS designed to solve microwave and high frequency problems.
COMSOL is general tool and it has very nice modules for each application. So, it is general tool, isn't it ?
