Classical index of refraction theory

[center o bass]

Is there such a thing as a classical theory for the index of refraction? I.e. are there expressions for the index of refraction $n$ in terms of other parameters like charge density?

If so, a reference would be much appreciated.

The index of refraction can be calculated with quantum solid state physics programs. The classical theory has been worked out in Born Huang, dynamical theory of crystal lattices.

It can be calculated in a gas and liquid state physics programs as well.
