Lorentz dispersion model for permeability

Post by qoelet »

Dear all,

I am trying to simulate materials with a frequency-dependent complex permeability, in particular with the Lorentz dispersion model, as shown in the following example:

Is there a way to set the permeability as a (complex) function of frequency in .SIF file?
Thank you in advance.

All the best,

Hi,

this is possible. Have a look into the Models Manual where several solvers for electromagnetic calcdulations are described, including the VectorHelmholtz solver for the high frequency regime.

HTH,
Matthias
