OPTICAL CONVEYOR. "The same methods used to project a single optical conveyor can project arrays of independent optical conveyors, allowing bidirectional transport in three dimensions."(2012). https://lnkd.in/ehevuXN View in LinkedIn

FIRST PROTOTYPE TRACTOR BEAM. "But at the microscopic level, an optical tractor beam has indeed been demonstrated: researchers have developed special optical beams that can pull nanoparticles opposite to the propagation direction." (2012). https://lnkd.in/eZUFQuD View in LinkedIn

MACRO BEAM. "Now, a step towards a device that works on macroscopic objects has been demonstrated by a group of researchers led by Michael MacDonald of the University of Dundee." https://lnkd.in/eYSRjM2 View in LinkedIn

MACRO BEAM. "They were able to scale the tractor beam up to handle centimeter-size objects, about 6 orders of magnitude larger than those manipulated by previous schemes." https://lnkd.in/eYSRjM2 View in LinkedIn

MACROSCOPIC TRACTOR BEAM. "We report an experimental acoustic tractor beam generated by an ultrasonic array operating on macroscopic targets (>1 cm)." The most powerful tractor beam to date. (Dundee University, 2014). https://lnkd.in/eCda3-n View in LinkedIn

BREAKTHROUGH. "A University of Dundee-based project to produce the first working acoustic tractor beam has been named one of the Breakthroughs of the Year for 2014 by Physics World, taking a place on the shortlist alongside the landing of the Philae probe onto a comet." https://lnkd.in/eG9zstT View in LinkedIn

SMALL SCALE BEAMS. "Recent advances in lightwave technology have already led to small-scale experimental demonstrations of tractor beams. However, the realization of long-range tractor beams has not gone beyond the realm of theoretical investigations." (2014). https://lnkd.in/eX6BjcT View in LinkedIn

LARGER SCALE BEAMS. "Here, we demonstrate the stable transfer of gold-coated hollow glass spheres against the power flow of a single inhomogeneously polarized laser beam over tens of centimetres. Additionally, by varying the polarization state of the beam we can stop the spheres or reverse the direction of their motion at will." (2014). https://lnkd.in/eX6BjcT View in LinkedIn

MOVING FLOATERS. "The ability to send a wave to fetch an object from a distance would find a broad range of applications. Here we show that when waves become three-dimensional as a result of the modulation instability, a floater can be forced to move towards the wave source." Ping pong ball drawn towards a wave generator." (2014). https://lnkd.in/eUvwy2B View in LinkedIn

HOVERBOARD. "Ever since Marty McFly took to the air in the 1989 classic Back to the Future II, humanity has been eagerly awaiting the arrival of a real, fully-functional hoverboard." https://lnkd.in/e4DD8kV View in LinkedIn
