Goos–Hänchen beam shift at total internal reflection with application to spatially dispersive media

In this paper the Goos–Hänchen beam displacement at total internal reflection is reviewed. The basic theory of the beam shift is discussed from a classical approach, and measurement of the shift is discussed. Other experimental results are outlined. The theory of finite beam shift at total internal reflection is summarized. An application to nonlocal media is discussed. Finally, recent developments are outlined with implication for beam shifts in spatially dispersive media.
