I use the frequency solver and unit cell boundary, but the simulation results don't agree with the paper (Plasmonic Oligomers: The Role of Individual Particles in...
Can anyone provide me a model of the metamaterial structure for CST - MWS . I have some difficults on port and boundary condition. The help would be greatly appreciated.Thanks a lot.
drude model hfss
How to define material properties according Drude model in hfss.
ε=1-[(ωp)^2/(ω(ω+iγ))]
For gold, ωp=1.37*10^16,γ=4.05*10^13,unit 1/s. when Freq wω=0.11Thz, ε=-114423*10^6+(2.32*10^7)i
When I edit Relative Permittivity=-114423, Dielectric Loss...
Re: Simulation of metamaterial with Periodic Boundary Condit
Could you tell me what's wrong with my project or my model?
Thanks.
I don't consider the lossy dielectrics in higher frequency in my calculation,because I don't know how to defining the frequency-dependent material properties...
If you do some work on metamaterial using HFSS, you don't get the effective dielectric constant directly. εeff can be determined from the transmission coefficient, which need retrieval procedure and is not simple.
Re: Simulation of metamaterial with Periodic Boundary Condit
I removed the SRR and simulated the S parameter of GaAs substrate. the curve which I ploted also show oscillating up and down,but have a little shifting. The oscillating should be derived from the transmiting of wave in...
I want to redo this article:
“Dynamical Electric and Magnetic Metamaterial Response at Terahertz Frequencies”
but I have find a big problem in the value of S11 and S21. I plot the S parameter which oscillating up and down. According to article, the sample is a planar array of SRRs fabricated...
research thesis on metamaterials
I am now try to simulate metamaterial using periodic BCs.The S21 results are also illogical.Do you know the wrong with your setup? Could you point it to me?
