## Nicolson Ross Weir (NRW) method, CST data calculations using matlab

Dear all, i have cst data for S-parameters (s11 and s21) and i want to calculate for complex permittivity and permeability on matlab using NRW. I tried several times but is not giving me the exact result. I went through several materials but my code doesn't work still. kindly help me out

## Fill factor Caculation

I'm modelling a metamaetrial slab on cst and get S-parameters from the results. Then I need to extract permeability and permittivity from the those parameters. I learnt a method based on the Lorentz Model, as mu(w)=1+(F*w^2)/(w0^2-w^2)+jrw Note there is a F called fill factor, but I don't know how to calculate in my model. Since

## Metamaterials: imaginary part of permittivity being negative

Hello dear friends, I'm working on a new metamaterial structure that have nonlinear properties with in a broad bandwidth. I have simulated the structure in cst and got the S11 and S21 of the structure. with the relations given in the articles calculated permittivity and permeability of the structure. but there is an amazing point in the result and

## CST: Define a Time Dependent Dielectric Constant of a material

From what I have seen cst does not have the ability to change permittivity/permeability with respect to time. You are going to have to make a custom code for that. If would recommend Finite-difference time-domain (FDTD). There is a great section about it here: Go to the academics section.

## Extraction of permeability and permmitivitty

Hi Folks, I am trying to make a simple cubic slab 2.5mm length, and width (attached ?Slab_pict?). I have used normal solid materials and given eps =5 and mue=3 in cst. I would like to see the same obtaining parameter (eps and mue) when I extracted data of S11 and S21 data with frequency (0-12 GHz) in matlab code. I have attached the Matlab code

## how can i add liquid crystal to my model in cst?

i have a split ring resonator model that must be in liquid crystal,how can i define liquid crystal in my model? this is the article Electrically tunable negative permeability metamaterials based on nematic liquid

## how to calculate negative permitivity and permeability ?

Hi. I'm not very familiar with metamaterial.But if your permitivity and permeability is frequncy dependent or negative or there isn't in cst library,you have to define it. go to cst library and add your material very simple. good luck!

## Help me make the following plot using CST

Hi Folks, I have redraw SRR unit cell. I used frequency domain with Zmax, Zmin port parameter. Thus, I already got S parameter results (S11, S21 db, magnitude smith, phase). Could you please let me know on how to make following plot using cst ?? 1. permeability (Mue)vs Frequency 2. Permitivitty (Eps) vs Frequency, and 3. Frequency vs Beta (

## Properties of Silicon Carbide

Hi, I am modelling high power waveguide loads on HFSS and cst. One material I need to model is silicon carbide. I cannot find anywhere a resourse that has the magnetic loss tangent and permeability. Also anything I find for the permittivity and electric loss tangent seems to contradict other sources. If anyone has or knows where I could find

## How PEC is defined in CST?

Hi How PEC is defined in cst? I mean the Electric conduct. , Relative permittivity , and relative permeability values?

## Magnetic coupling simulation

Dear all, I would like to simulate coupled coil, for example 3D solenoids or planar inductors. As the received power depends on numerous parameters (number of turns, distance, symmetry, frequency, permeability, even unconsidering non-linear phenomenoms), so magnetic field produced and received, simulation seems useful. Do you recommend som

## help in CST - changing the equilibrate mesh ratio

Sorry I have no specific advice regarding your particular problem. I've seen this happen alot with this software. Sometimes it's understandable; for example, maybe you have some small feature that would be expected to have a relatively large effect, e.g., a small air gap in a high permeability magnetic core, and it just doesn't get meshed proper

## how to represent refraction index with CST?

i am working about patch antenna with metamaterials (the substrat=dielectriq+SRRs) . my work is based on cst microwave studio. i want to represent the refraction index "n" of substrat and permittivity and permeability of substrat with cst simulator. how to represent refraction index, permittivity and permeability with (...)

## <CST FD-Solver> Use experimental values of material pa

Is it possible to force the frequency domain of cst MWS to use the material parameters (permittivity/permeability versus frequency )defined in a file or a list? I know that it is possible to load material parameters (permittivity/permeability versus frequency) from a file and use several fitting schemes. But for the FD solver such a fitting (...)

## How to measure permeability at THz using HFSS?

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
