Wireless device converts 'lost' energy into electric power
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar ...
Plasmonic crystal alters to match light-frequency source
Gems are known for the beauty of the light that passes through them. But it is the fixed atomic arrangements of these crystals that determine the light frequencies permitted passage.
A new way of seeing: Metamaterial lens has ten times more power
(Phys.org) —A lens with ten times the resolution of any current lens, making it a powerful new tool for the biological sciences has been developed by researchers at the University of Sydney.
'Nanoimprinting' technique makes it possible to fabricate visible-light-bending metamaterials at unprecedented scales
Artificial materials containing arrays of metal nanostructures can interact with light in useful and interesting ways. One of the most interesting possible uses of such 'metamaterials' is to bend light around ...
Got 15 minutes? Invisibility cloak coming up
Made-to-order materials: Engineers focus on the nano to create strong, lightweight materials
(Phys.org) —The lightweight skeletons of organisms such as sea sponges display a strength that far exceeds that of manmade products constructed from similar materials. Scientists have long suspected that ...
Mathematician designs event cloaking device without using metamaterials
Muscles act as metamaterials due to collective behavior, physicists show
Researchers suggest magicians' mirror tricks could be used as large scale cloaking devices (w/ video)
Metamaterial flexible sheets could transform optics
(Phys.org) —New ultrathin, planar, lightweight, and broadband polarimetric photonic devices and optics could result from recent research by a team of Los Alamos National Laboratory scientists. The advances ...
Meta-transmitarray offers unprecedented control of light on subwavelength scales
Researchers develop metamaterials able to control spread of light
Researchers tackle collapsing bridges with new technology
In this month's issue of Physics World, an international group of researchers propose a new technology that could divert vibrations away from load-bearing elements of bridges to avoid catastrophic collap ...
