Rotational Mechanical Effects of Sound

The exploratory studies on sound-matter interaction are one of the most promising directions as fundamental research which can be used practically in rheology, medical imaging and other contactless manipulations. Expected application potential of the study of rotational mechanical effects of sound invites a better understanding of acoustic radiation torques and further fundamental experimental investigations. The research project proposes to explore experimentally new facets of the rotational mechanical effects of sound based on the use of acoustic vortex beams, which are characterized by a helical wavefront bearing on-axis phase singularity. Indeed, depending on the specific wave matter interaction, acoustic vortex beams can induce various rotational mechanical effects, such as angular displacements, spinning or orbiting motions.
