Quantum-mechanical calculations for the dielectric permittivity tensor
in incommensurately modulated ionic-type insulators are carried out. The
microscopic Fourier components of the tensor are obtained. The role of
different reciprocal lattice vectors in the optical response of crystal
is clarified
Key words: insulator, dielectric permittivity tensor, incommensurate
phase
