In this paper, we theoretically show that small particles compared to the wavelength can be trapped and assembled in three dimensions with synchronized spherical vortices. The particles can be approached both laterally and axially and, for each configuration, the maximum assembly speed can be determined by balancing the Stokes' drag force and the critical radiation force. These theoretical results provide guidelines to design acoustical tweezers able to trap and assemble particles in three dimensions.Show less >
