Hi All,
I am currently trying to simulate split ring resonators on a substrate with a dispersive permittivity. I am having trouble figuring out how to convert the coefficients from a lorentz dispersion model to the coefficients in meep. The equation I am using for the analytical model is depicted below. The constants are sigma0=3.636, f0=6.278,gamma0=0.0660, sigma1=0.00470,f1=1.653, gamma1=0.226, epsilon infinity=13.3727. I've tried many things and nothing seems to replicate the analytical model.
