Homogeneous models for bianisotropic crystals
Abstract
We generalized to bianisotropic structures a formalism, based on the Bloch method to define the effective dielectric tensor of anisotropic crystals in the long-wavelength approximation. We illustrate our procedure by applying this to a 1D magneto-electric Smectic C*-type structure. The resulting equations confirm that the presence of dielectric and magnetic susceptibilities in the periodic structures generates magneto-electric pseudo-tensors for the effective medium. Their contribution to the optical activity of structurally chiral media can be of the same order of magnitude as the one present in dielectric helical-shaped crystals.
