Interplanetary precision laser could reach to Mars and beyond
Meta-transmitarray offers unprecedented control of light on subwavelength scales
New method of quantum entanglement vastly increases how much information can be carried in a photon
A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are ...
Engineers break power and distance barriers for fiber optic communication
Electrical engineers have broken key barriers that limit the distance information can travel in fiber optic cables and still be accurately deciphered by a receiver. Photonics researchers at the University ...
Catalyst that converts carbon dioxide to carbon monoxide in water
Scientists print low cost radio frequency antenna with graphene ink
Scientists have moved graphene—the incredibly strong and conductive single-atom-thick sheet of carbon—a significant step along the path from lab bench novelty to commercially viable material for new electronic ...
Tabletop experiment could detect gravitational waves
(Phys.org)—A coin-sized detector might observe gravitational waves before the giant Laser Interferometer Gravitational-Wave Observatory (LIGO), according to two Australian physicists.
Engineers efficiently 'mix' light at the nanoscale
The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but ...
Lighter, cheaper radio wave device could transform telecommunications
Researchers at the Cockrell School of Engineering at The University of Texas at Austin have achieved a milestone in modern wireless and cellular telecommunications, creating a radically smaller, more efficient ...
Nanoribbon film keeps glass ice-free: Team refines deicing film that allows radio frequencies to pass
Rice University scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass.
Researchers enable robots to see through solid walls with Wi-Fi (w/ Video)
(Phys.org) —Wi-Fi makes all kinds of things possible. We can send and receive messages, make phone calls, browse the Internet, even play games with people who are miles away, all without the cords and wires ...
No-power Wi-Fi connectivity could fuel internet of things reality
Imagine a world in which your wristwatch or other wearable device communicates directly with your online profiles, storing information about your daily activities where you can best access it – all without ...
New 'T-ray' tech converts light to sound for weapons detection, medical imaging
A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range.
