# PyOptMat
PyOptMat is a python package providing dielectric constants of optical materials
using data from the
[refractiveindex.info database](http://refractiveindex.info/)
developed by [Mikhail Polyanskiy](https://github.com/polyanskiy).

The parameters of dielectric functions for noble metals are derived by fitting
the data shown in [1] or [2], refering to the parameters used in [3] and [4].
