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

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

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

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

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

OPTICAL CONVEYOR. "Trapped objects can be moved selectively upstream or downstream along the conveyor by appropriately changing the Bessel beams' relative phase." https://lnkd.in/ehevuXN View in LinkedIn

TRACTOR BEAM. "We experimentally demonstrate a class of tractor beams created by coherently superposing coaxial Bessel beams. These optical conveyors have periodic intensity variations along their axes that act as highly effective optical traps for micrometer-scale objects." https://lnkd.in/ehevuXN View in LinkedIn

TUNABLE GUIDED WAVES. "Tunable bipolar optical interactions between guided lightwaves. Here we experimentally demonstrate a bipolar optical force between coupled nanomechanical waveguides. Both attractive and repulsive optical forces are obtained." (2009). https://lnkd.in/eWz8PbZ View in LinkedIn

PRIOR ART. "The optical binding forces between guided lightwaves in dielectric waveguides can be either repulsive or attractive. So far only attractive force has been observed." (2009). https://lnkd.in/eWz8PbZ View in LinkedIn

MOVING WAVE. "In general terms, a tractor beam (short for attractor) is a traveling wave that can move a targeted object along its length back to the source, or hold it in place at a designated distance from the source. In Star Trek, the beam was an “attenuated linear graviton beam,” produced by a graviton generator." https://lnkd.in/enw54RD View in LinkedIn
