Reference work entry


Collective name for a number of techniques dealing with the measurement and interpretation of the change in the polarization state of a polarized beam of radiation which is reflected from a surface.

From this change, optical properties of the reflecting surface can be derived.

Theory and Application

Basic Theory for Reflection and Transmission at an Interface and the Basic Ellipsometry Equation

In Fig. 1 the beam trajectories are sketched for a wave incident on a plane interface between two media having a real refractive index n 1 and n 2, respectively. The incoming beam with amplitude E 1 is reflected by the interface, giving a reflected beam with amplitude E 2 and a transmitted beam with amplitude E 3.
