Anisotropic materials differ from isotropic material properties in that their density, electrical conductivity, magnetic permeability or their refraction

are directional and that waves passing through them change their properties with direction. This applies equally to the electrical, magnetic or optical properties, which change with direction and waves. For example, these may be electromagnetic waves that propagate in a particular plane of polarization. In the case of light waves, anisotropic propagation arises from different refractive indices

or from polarization. One characteristic of anisotropic liquid crystals is their state of aggregation, which changes with temperature and assumes other states, like that of isotropic materials. The anisotropic states of aggregation are: solid - liquid crystalline - isotropic liquid - gaseous.
