A linear system of differential equations with constant coefficients which describes diffraction of light with TM-polarisations on periodical nonabsorbal mediums was obtained on the basis of Maxwell's equations. The electromagnetic field in a periodic structure volume is represented as a sum of plane waves with coefficients which depend on coordinates. Conditions of diffraction angles of different orders beams have been obtained. Systems of differential equations for TM and TE polarisations have been brought together.
