An acoustic “tractor beam” that can pull an object by firing sound waves at it has been created by physicists in the UK and US. The beam was made using a commercial ultrasound surgery system and ...

The tractor beam was able to move a hollow triangular object forward 1cm This was done with a device that exerted pressure using sound waves Device could have applications in treating cancer and ...

While beam-shaping strategies have allowed researchers to sculpt the cross-sectional shape of laser spots—using, for example, triangular beams to carve triangular channels—the interaction of such ...
