Abstract

In this article the relation between the directions of eigen-polarizations of light waves with the stored electrical energy in an anisotropic medium is discussed, and it is shown that each of two eigen-polarizations correspond to an extremum in the stored electrical energy. So for a given direction of a wave vector and a given magnitude of displacement electric field vector, there exist two extrema that result in the eigen-polarizations. It is shown that this conclusion also holds for plane waves in materials with anisotropic permeability tensor. An interesting effect is found that normal to the crystal axes, the distribution of energy in different directions is uniform. THerefore, for uniaxial crystals, only one of such plane directions could exist while for biaxial crystals, two such planes could be found, corresponding to the two optical axes.
