Annotation

The full energy of radiation of fixed distribution of electrical charges with instantaneous change in the properties of a two-axis crystal is calculated using representation of the tensor of dielectric permittivity of a medium in a covariant form (not a function of the selection of the coordinate system). The optical characteristics of the radiated waves are found in a linear approximation in terms of the small parameter - the degree of anisotropy of the medium, and an expression for the radiation energy in the case when only the degree of anisotropy of the medium is changed is analyzed.
