Figure 1.Incident, transmitted, and reflected electromagnetic waves at the surface of a material. The angle of incidence shown is the Brewster angle, for which the p-polarized wave in the lower medium points along the reflection direction. The s wave is polarized perpendicular to the plane of the page.

Figure 2.Linearly polarized incident and elliptically polarized reflected waves. These represent the trajectories of the respective electric field vectors in the complex plane. Ep and Es are the p and s components of the electric field; |rp| and |rs| are the magnitudes of the complex reflectances.
