Daniel Axelrod created a form of fluorescent microscopy using this effect which is used to image membrane surfaces. In one system, this phenomenon is induced in a core substance by the interface with a cladding. One variety of this effect relies on the transmission of energy via evanescent wave coupling. This phenomenon can induce a small lateral shift in linearly polarized (*) light, or a perpendicular phase shift in circularly polarized light; those are the Goos-Hanchen and Imbert-Federov effects. The angle at which this phenomenon occurs is

This phenomenon can induce a small lateral shift in linearly polarized (*) light, or a perpendicular phase shift in circularly polarized light; those are the Goos-Hanchen and Imbert-Federov effects. The angle at which this phenomenon occurs is equal to the arcsine of n sub two over n sub 1, and it occurs repeatedly in a fiber optic cable. For 10 points, name this phenomenon that occurs when incident light strikes a refractive surface at greater than the critical angle, and is bounced back into the first medium.
