[Meep-discuss] in regards to material-dispersion.ctl

2018-01-18 Thread Heligman, Daniel M.
Hi all, Can anyone tell me exactly how to grab the epsilon data from material-dispersion.ctl. The tutorial only tells me to grep the frequencies and epsilon and not much more. And once I have obtained the data, what are the means of analyzing the data. Best, Daniel Heligman

2018-01-18 Thread Heligman, Daniel M.
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
