treams.Material.nmp¶
- property Material.nmp¶
Refractive indices of both helicities.
The refractive indices are defined by \(n_\pm = \sqrt{\epsilon \mu} \pm \kappa\), with an enforced non-negative imaginary part.
Note
The refractive indices returned depend on the chirality parameter. For an alternative definition of the refractive index, see also
