Abstract
In this paper a general expression is given for the wave vector- and frequency-dependent dielectric susceptibility tensor of a composite perfect lattice with an arbitrary number of fixed nonpolar molecules with given polarizability tensor in a unit cell. The general expression is applied to a lattice of point dipoles and quadrupoles. The dielectric susceptibility tensor is in particular studied with first order spatial dispersion.
