Closed-form expression for the Goos-Hänchen lateral displacement
Closed-form expression for the Goos-Hänchen lateral displacement
The Artmann formula provides an accurate determination of the Goos-Haenchen lateral displacement in terms of the light wavelength, refractive index and incidence angle. In the total reflection region, this formula is widely used in the literature and confirmed by experiments. Nevertheless, for incidence at critical angle, it tends to infinity …
