Determination of optical constants using pseudo-Brewster angle and normal incidence reflectance measurements.

A new technique is described through which the refractive index and extinction coefficient of an isotropic solid can be determined using measurements of normal incidence reflectance and pseudo- Brewster angle. We demonstrate that the expected accuracy of this method is better than that of other reflectivity-based techniques, due to the increased accuracy with which the experimental parameters can be measured.
