Researchers in China and Singapore show that particle shape and rotation angle can reverse optical torques and freeze ...
A light beam with orbital angular momentum can produce the rotational analog of the Doppler effect on an ion. A vortex light beam is one whose wave fronts rotate like a corkscrew, endowing the beam ...
A rotational concept stood up in Europe and now extended to Africa is providing valuable lessons in ways to sustain partnerships despite force reductions and tightened resources. Marine Forces Europe ...
