mnpbem-material
mnpbem-material implements dielectric-function models used in plasmonic electrodynamics.
The module provides analytical material models and tabulated optical constants for metals such as Au, Ag, and Al.
Features
- Constant dielectric model for homogeneous media.
- Drude dielectric model for free-electron metals.
- Tabulated
(E, n, k)optical constants with wavelength-domain interpolation. - Ready-to-use datasets for common plasmonic materials.
Implemented Formulations
1. Constant Dielectric Function
For wavelength-independent permittivity:
The wave number is:
2. Drude Model
For free-electron metal response:
Energy-wavelength conversion used in the implementation:
3. Tabulated Material Model
Given tabulated optical constants (energy, refractive index, extinction), the dielectric function is:
