redOrbit Staff & Wire Reports - Your Universe Online Researchers from Duke University have come up with a method of wirelessly charging electrical devices using low-frequency magnetic fields, according to a study appearing in Friday’s edition of the journal Nature Scientific Reports. “The ability to wirelessly power electrical devices is becoming of greater urgency as a component of energy conservation and sustainability efforts,” the researchers wrote. However, due to health...

Research Helps Lay Out Theory For Metamaterials That Act As Analog Computer
2014-01-10 09:54:04

[ Watch The Video: Explaining Metamaterials ] University of Pennsylvania The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate light in the way electronic circuitry manipulates the flow of electrons. Now, the birthplace of the digital computer, ENIAC, is using this technology in the rebirth of analog computing. A study by researchers at the University...

Researcher Helps Pioneer Flat Spray-on Optical Lens
2013-05-23 15:28:19

University of British Columbia A University of British Columbia engineer and a team of U.S. researchers have made a breakthrough utilizing spray-on technology that could revolutionize the way optical lenses are made and used. Kenneth Chau, an assistant professor in the School of Engineering at UBC's Okanagan campus, is a key investigator among colleagues at the National Institute of Standards and Technology in Maryland. Their work — the development of a flat lens — is...

Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials — artificial nanoconstructs whose optical properties arise from their physical structure rather than their chemical composition. Engineering a unique two-dimensional sheet of gold nanoantennas, the researchers were able to obtain the strongest signal yet of the photonic spin Hall effect, an optical...

Scientists are reporting development of a revolutionary new lens – flat, distortion-free, so small that more than 1,500 would fit across the width of a human hair – capable in the future of replacing lenses in applications ranging from cell phones to cameras to fiber-optic communication systems. The advance, which could lead to smart phones as thin as a credit card, appears in ACS' journal Nano Letters. Federico Capasso and colleagues explain that the lenses used to focus light...

Perfect Image Offered By Flat Lens

Ultrathin wafer of silicon and gold focuses telecom wavelengths without distortion Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. At a mere 60 nanometers thick, the flat lens is essentially two-dimensional, yet its focusing power approaches the ultimate physical limit set by the laws of diffraction. Operating at telecom wavelengths...

More than one hundred years after the pioneering inventor Nikola Tesla first became fascinated with wireless energy transfer, the spread of mobile electronic devices has sparked renewed interest in the ability to power up without plugging in. Now researchers from Duke University in Durham, N.C., and the Mitsubishi Electric Research Laboratories in Cambridge, Mass., have proposed a way to enhance the efficiency of wireless power transfer systems by incorporating a lens made from a new class of...

Michigan Tech Researcher Nears Creation Of Superlens

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones. No one has yet made a superlens, also known as a perfect lens, though people are trying. Optical lenses are limited by the nature of light, the so-called diffraction limit, so even the best won´t usually let us see objects smaller than 200 nanometers across, about...

Research highlights advances in nano-optics Light-matter interaction at the nanometer scale has turned into a very fast-growing field of research known as nano-optics.  To highlight breakthroughs in the specific areas of nano-optics known as nanoplasmonics and metamaterials, the editors of the Optical Society's (OSA) open-access journal Optical Materials Express (OMEx) have published a special Focus Issue on Nanoplasmonics and Metamaterials. The issue is organized and edited by Guest...

Electrical engineers at Duke University have determined that unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires. This advance is made possible by the recent ability to fabricate exotic composite materials known as metamaterials, which are not so much a single substance, but an entire man-made structure that can be engineered to...
