hfss 11 resonator
All,
I don't know if this is still desired or not, but I have been able to simulate the unit cell shown in Figure 2 of the paper, "Electromagnetic parameter retrieval from inhomogeneous metamaterials." The magnitudes of for my S-parameters match what is shown in Figure 3a. The phases of my S-parameters are opposite of what is shown in Figure 3b (i.e. I can plot the correct phase if I plot -Arg(S21)).
Based on these results, I took the S-parameters (I inverted my result for Arg(S21)), imported them into Matlab, and extracted the refractive index, the impedance, the permittivity, and the permeability. My graphs precisely match those shown in Figures 3c, 3d, 3e, and 3f. I will gladly share these codes with anyone that likes them--I didn't post initially because this thread has been inactive for awhile and I didn't want to waste time if it wasn't necessary.
I would like to know why the phases for my S-parameters are opposite to what are shown in the paper. Someone posted this was because the authors use an e^(-iwt) time convention versus the engineering convention of e^(jwt). I know this difference in convention causes issues, but I don't understand it enough to know the exact impacts. Any help would be great.
Pleasant day,
Jeff
