Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or two-dimensional (2D) images produced by precisely controlling the shape and ...
A programmable terahertz chip combines penetrative sensing, nonvolatile optical encoding, and hardware preprocessing, classifying vehicle motion with 92.3% accuracy and recovering encoded information ...
Abstract: Holographic MIMO (HMIMO) antennas are emerging as a transformative technology for next-generation wireless networks, offering unprecedented control over EM wave propagation through ...
One important form is called an optical vortex beam. Unlike an ordinary light beam with a flat wavefront, an optical vortex beam has a twisted, corkscrew-like phase structure and a dark center, much ...
The metasurface is the six-millimetre-sized circle at the centre of the disk. (Courtesy: Noah Rubin) A compact optical ...
Free-space optical (FSO) communication has emerged as a promising technology for next-generation wireless and optical communication networks due to its ...
Amazon Leo has filed with the FCC to deploy up to 5,105 new satellites designed to use Globalstar’s spectrum to bring voice, ...
