I was solving a very complex coil, there was always a problem saying error accessing 1D result storage. Then solver stops automatically. I do not understand why. Note there are no other errors, just some low quality elements in my meshing. I am using high frequency problem and frequency domain...
I found a lot of papers extract permeability of a metamaterial slab based on the Lorentz models. However, I cannot find a paper introduce how to decide plasma frequency in magnetic field. The only thing I get is an equation used in Split ring resonators which relate it with a filling factor as...
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...
