Atom tamers Top left: Schematic of how a metasurface shapes a single beam of light into multiple tightly focused beams in a single step. These beams form a series of optical tweezers to trap ...

Abstract: A low-cost, low-profile, electronically controlled millimeter-wave antenna array with two-dimensional wide-angle beam scanning capability is presented. It consists of a planar waveguiding ...

Abstract: Conventional three-dimensional (3D) photoacoustic imaging (PAI) requires the use of fully addressed two-dimensional matrix or hemispherical matrix arrays, which are limited by their high ...
