Goos–Hänchen effect

The Goos–Hänchen effect, named after Hermann Fritz Gustav Goos (1883–1968) and Hilda Hänchen (1919–2013), but first suggested by Isaac Newton (1643–1727), is an optical phenomenon in which linearly polarized light undergoes a small lateral shift when totally internally reflected. The shift is perpendicular to the direction of propagation in the plane containing the incident and reflected beams. This effect is the linear-polarization analog of the Imbert–Fedorov effect.

Acoustic analog of the Goos–Hänchen effect is known as Schoch displacement.
