Abstract

Microwave phase measurements, using the Robertson homodyne detection method, have been made in the field outside a dielectric prism after microwave energy has experienced total internal reflection. The phase changes that occur in this case are explained by extending Artmann's theory of the Goos-Hänchen effect to microwave optics. Satisfactory agreement between the theory and measurements has been obtained for angles of incidence from 40 to 50° on a dielectric boundary for which the critical angle is 36.4°.
