Paper Abstract

A reflected light by a substrate becomes zero when H-polarized light is incident at the Brewster angle. Stacking many identical substrates together forms a multi-layer structure. The valley of this reflected intensity pattern centered at the Brewster angle becomes narrower due to the overlapping of these similar reflections from many parallel interfaces of air and substrates. Thus, measuring the Brewster angle of this multi-layer structure leads to an accurate determination of the substrate index.
