Wikipedia Overview
The Goos–Hänchen effect, named after Hermann Fritz Gustav Goos and Hilda Hänchen, was first theorized by Isaac Newton, and is an optical phenomenon in which a finite-width beam of light undergoes a small lateral shift when totally internally reflected. The shift arises because a bounded beam comprises a continuous distribution of plane wave components with differing wave vectors. The Fresnel reflection coefficients are both polarization and angle dependent, so each plane wave component acquires a different phase shift upon reflection. The superposition of these phase-shifted components displaces the reflected beam's centroid along the interface. The magnitude of the shift is small, and it depends on the beam's polarization state, the wavelength, and the angle of incidence. It is among the most studied non-specular reflection phenomena in optics.
