Additional information
This paper describes the experimental demonstration of a real “sonic screwdriver”, in which an ultrasound beam formed into a helix both levitates and spins a target in water. This work confirmed experimentally for the first time fundamental theories about the angular momentum that can be carried by beams, used in topics ranging from communications theory to biophotonics. This research formed a very exciting part of the Sonotweezers acoustic manipulation research programme (£4.2m EPSRC grant, EP/G01213), generating significant interest in the general press, including a spot on the BBC evening news, and has led to several invited talks by the authors.
