In this paper evolution of thick anisotropic gratings formation in photomonomer–liquid crystal mixture is modeled. The polymer and monomer concentrations’ distributions are obtained from modeling of grating formation process. Distributions of dielectric permittivities from Lorentz-Lorenz and more simple approximate formulas are obtained. The comparison of received distributions and appropriate diffraction efficiencies for $s-$ and $p-$polarized probe beams are done. It appears, that diffraction efficiencies calculated by exact and approximate distributions qualitatively coincide, however there is a quantitative difference and it depends on polarization of the probe beam.
Keywords: Grating formation process, photomonomer–liquid crystal mixture.
