The development in acoustic tractor beams comes from the University of Bristol. Acoustic tractor beams work on the basis of controlling sound in order to hold particles in mid-air. In a sense the beam ...

An acoustic tractor beam that can bend sound around an obstacle to levitate an object on the other side has been created by researchers in the UK. Dubbed SoundBender, the device combines an ultrasound ...

Researchers at TMOS, the ARC Centre of Excellence for Transformative Meta-Optical Systems, have taken an important first step in the development of metasurface-enabled tractor beams—rays of light that ...

The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.
