On the relations of microscopic and averaged material parameters in composite media

This work is devoted to the fundamental question of the relationship between local, external and averaged electrostatic field in nonpolar anisotropic dielectrics. Artificial dielectrics are under consideration. This makes possible to be restricted to classical electrostatics without additional approximations. We offer an approach that is an alternative to the classic deduction of the Lorenz-Lorentz formula. This makes it possible to take into account the interaction between inclusions in the artificial dielectrics with complex inner geometry and dielectric permittivity. Numerical calculation for oblique-angled lattices was carried out.
