A new twist in the properties of light
Light has some well-established dynamical properties that have defined our understanding of electromagnetic radiation for over a century. Two of the most fundamental of these properties are that photons of ...
Research finds 'tunable' semiconductors will allow better detectors, solar cells
(Phys.org) —One of the great problems in physics is the detection of electromagnetic radiation – that is, light – which lies outside the small range of wavelengths that the human eye can see. Think X-rays, for example, ...
Scientists twist sound with metamaterials
A Chinese-U.S. research team is exploring the use of metamaterials—artificial materials engineered to have exotic properties not found in nature—to create devices that manipulate sound in versatile and ...
New study reveals communications potential of graphene
Providing secure wireless connections and improving the efficiency of communication devices could be another application for graphene, as demonstrated by scientists at Queen Mary University of London and ...
US Navy ready to deploy laser for first time
Some of the Navy's futuristic weapons sound like something out of "Star Wars," with lasers designed to shoot down aerial drones and electric guns that fire projectiles at hypersonic speeds.
Researchers take magnetic waves for a spin
Researchers at New York University have developed a method for creating and directing fast moving waves in magnetic fields that have the potential to enhance communication and information processing in computer chips and ...
EPFL scientists have developed an innovative mathematical method to greatly improve computer modeling of metamaterials.
Knock, knock, knocking on the proton's weak charge
(Phys.org) —The weak force is, for laymen, the least known of the quartet of interactions that run the universe as we know it.
Text message using vodka: Molecular communication can aid communication underground, underwater or inside the body
Scientists have created a molecular communications system for the transmission of messages and data in challenging environments such as tunnels, pipelines, underwater and within the body.
Pulses immobilize cars with RF Safe-Stop from e2v
Submillimeter wavelengths shine through the intergalactic dust
(Phys.org) —Where do you go to look at the stars? Away from city lights, certainly. But if you're serious about peering far out into space, to the observable edges of our universe, at submillimeter wavelengths, ...
Scientists create perfect solution to iron out kinks in surfaces
A new technique that allows curved surfaces to appear flat to electromagnetic waves has been developed by scientists at Queen Mary University of London.
New approach advances wireless power transfer for electric vehicles
Researchers from North Carolina State University have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver – moving engineers closer to ...
