摘要：
Diffraction of light in heterogeneous medium with non-uniform spatial distribution of dielectric nanoparticles taking into account absorption of light is investigated. Influence of dimensional (geometric) effects of nanoparticles on the reflection and transmission curves is shown. In particular, by changing the concentration of dielectric nanoparticles in the medium, complete elimination of side oscillations and suppression of the "tails" of the diffraction reflection curve is achieved. The possibility of controlling the hardware function of acousto-optic devices by changing the material, concentration, size, shape and spatial orientation of the inclusions, as well as the polarization of the incident radiation is shown.
