Analysis reveals significant absorption and scattering of sound in suspensions, suggesting applications in developing metamaterials.
In this paper, the absorption and scattering of sound in suspensions with rotational movements of particles is analyzed. Such rotational (angular) oscillations are possible if the center of mass of the particle is shifted relative to the center of buoyancy. In such suspensions, there is a specific attenuation and scattering of sound. These effects can be used in the tasks of diagnosing suspensions in natural environments and in technological processes, as well as in the creation of metamaterials.
