摘要：
A method for trapping of particles in a wideband vortex acoustic field in air is proposed. The placement of radiators on the surface of a spherical belt with a radial shift, which ensures the formation of a vortex field, is considered. The results of numerical calculations and of experimental studies are presented. It is shown that in a wideband field there is only one point at which a stable trapping of a particle is maintained.
