Acousto-optical properties of heterogeneous media with a nonuniform distribution of nanoparticles

The possibility of efficiently using metamaterials in acousto-optics has been demonstrated. Diffraction reflection and transmission curves of metamedia with a nonuniform spatial distribution of nanoparticles have been studied taking into account absorption of light. The influence of size (geometric) effects of nanoparticles on diffraction reflection and transmission curves has been shown. In particular, it has been shown that the variation of the concentration of dielectric nanoparticles in a medium allows completely removing extraneous oscillations and suppressing the “tails” of the diffraction reflection curve. It has been demonstrated that the response function of acousto-optical devices can be controlled by varying the material, concentration, size, shape, and spatial orientation of inclusions, as well as the polarization of incident radiation.
