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.
Metamaterials and transformation optics control light on a microchip
Using a combination of the new tools of metamaterials and transformation optics, engineers at Penn State University have developed designs for miniaturized optical devices that can be used in chip-based optical ...
Researchers find a 'glitch' in pulsar 'glitch' theory
(Phys.org)—Researchers from the University of Southampton have called in to question a 40 year-old theory explaining the periodic speeding up or 'glitching' of pulsars.
Silver nanocubes make super light absorbers
Microscopic metallic cubes could unleash the enormous potential of metamaterials to absorb light, leading to more efficient and cost-effective large-area absorbers for sensors or solar cells, Duke University ...
New optical tweezers trap specimens just a few nanometers across
(Phys.org)—A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Stanford researchers have found a new way to trap particles smaller than ...
Explosive origins for cosmic dust
(Phys.org)—The European Space Agency's Herschel Space Observatory has produced an intricate view of the remains of a star that died in a stellar explosion a millennium ago. This new view provides further ...
New study furthers Einstein's 'theory of everything'
(Phys.org)—Sussex physicists have taken a small step towards fulfilling Einstein's dream of proving there is only one fundamental force in nature.
Electromagnetic disaster could cost trillions and affect millions. We need to be prepared
Predicting or worrying about disasters is a popular pastime. But we tend to take notice when somebody with money at stake becomes concerned.
US village is cell phone free and loving it
In this rural speck of hyper-connected America, it's easier to hear a cow moo than a cell phone ring. That's because Green Bank is home to the world's most sensitive radio telescope, a device that catches the birth and death ...
A new generation of storage—ring
A bright synchrotron source that emits over a wide part of the electromagnetic spectrum from the infrared to hard X-rays is currently being built in Lund, Sweden. The MAX IV facility presents a range of technical ...
Building the world's most sensitive detectors: A conversation with Rana Adhikari
Caltech professor of physics Rana Adhikari has been on a singular quest for 15 years: to detect gravitational waves.
Reinterpreting dark matter
Tom Broadhurst, an Ikerbasque researcher at the University of the Basque Country (UPV/EHU), has participated alongside scientists of the National Taiwan University in a piece of research that explores cold ...
N.Korea developing electromagnetic pulse weapons: S.Korea
South Korea's spy agency said Monday that North Korea was using Russian technology to develop electromagnetic pulse weapons aimed at paralysing military electronic equipment south of the border.
Array of perfect nanometer-scale spheres that can control the flow of visible light may find use in invisibility cloaks
The optical properties of a material are predominantly determined by its constituent atoms and electrons and the way that these respond to electromagnetic waves. In natural materials, the diversity of possible ...
