Dispersion and symmetry properties of anisotropic photonic crystals ofarbitrary geometry and dimension

摘要

This work presents a fully vector plane wave method suitable for eigenwaves characteristics calculation for periodic dielectric media with arbitrary geometry and dimension, consisting of either isotropic or anisotropic materials. Using the method concerned, the influence of anisotropic material molecules reorientation in a photonic crystal on the symmetry properties of the dispersion surface of the latter. The work explains how the 2D anisotropic photonic crystal Brillouin zone shape depend on the anisotropic molecules orientation
