Please see the article in J. Ellipsometry is a very sensitive optical method for the characterization of surfaces and thin film layers. Both the ellipsometric parameters and reflectivity are measured by one spectroscopic ellipsometer. Initially it was a little DOS program for a Drude-Lorentz fitting of the reflection coefficient (this is where its name comes from). . It makes use of the fact that the polarization state of light may change upon reflection from a surface, and that this change carries information about the surface’s drude properties. Drude’s model predicts monotonous decrease of εr(ω) for decreasing photon energy.
