Abstract
Up till now we have assumed the electrodynamics of a non-magnetic stratified system to be characterized by one dielectric function ε(z).This is often a very good approximation: for example in the case of monatomic fluids, where a liquid—vapour interface needs two dielectric functions ε x (z) and ε z (z) for specification of the electrodynamics, the difference between these is small (Lekner 1983). On the other hand molecular systems can have strong anisotropy due to orientation of the molecules, extreme examples being liquid crystals. Other cases of interest are anisotropic crystals, and anisotropy in ionospheric propagation of radio waves due to the earth’s magnetic field. Simple examples of reflection in the presence of anisotropy will be discussed here, with emphasis on the interplay of anisotropy and stratification in their effect on reflectivities and ellipsometric measurements.
