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 - Material.n().- Returns:
- tuple
