Investigation of the Rayleigh Critical Angle Phenomenon for the Characterization of Surface Properties

Abstract

A series of experiments on single crystals and other materials of a controlled nature have been preferred. These experiments have provided strong constraints on the interpretation of critical angle measurements made with an apparatus which employs a focused acoustic source rather than a plane wave source. Certain 'anomalous' measurements reported earlier on uncontrolled materials have been seen again in these controlled materials.
