Meta-transmitarray offers unprecedented control of light on subwavelength scales
New technology may double radio frequency data capacity
A team of Columbia Engineering researchers has invented a technology—full-duplex radio integrated circuits (ICs)—that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception ...
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 ...
Self-rolled tubes make miniature electronics
Researchers develop technique for making light-bending 'raspberry-like metamolecules'
The field of metamaterials is all about making structures that have physical properties that aren't found in nature. Predicting what kinds of structures would have those traits is one challenge; physically ...
Metamaterials used to make metamirrors capable of reflecting one frequency and ignoring all others
Do-it-yourself invisibility with 3-D printing
Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.
Research team develops tattoo-like skin thermometer patch
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 ...
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.
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.
Near error-free wireless detection made possible
(Phys.org) —A new long-range wireless tag detection system, with potential applications in health care, environmental protection and goods tracking, can pinpoint items with near 100 per cent accuracy over ...
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 ...
