Team develops new metamaterial device
An engineered metamaterial proved it can function as a state-of-the-art device in the complex terahertz range of the electromagnetic spectrum, setting a standard of performance for modulating tiny waves of radiation, according to a team of researchers from Boston College, the Los Alamos and Sandia national laboratories, and Boston University. view more (2009-02-25)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)
Researchers bridge the 'terahertz gap' with new tunable metamaterial
A frequency-agile metamaterial that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered by a team of researchers from Boston College, Los Alamos National Laboratory and Boston University. view more (2008-04-16)
Nanocups brim with potential
Researchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices. view more (2009-03-16)
Discovery at UAB brings us nearer to making the dream of invisibility true
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light - very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. view more (2009-07-08)
Beyond the looking glass
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway. view more (2009-08-13)
Scientists step closer to realising invisible technology
A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. view more (2007-05-04)
New metamaterials that bend light backwards bring invisibility cloaks 1 step closer
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and... view more...

Theoretical blueprint for invisibility cloak reported
Using a new design theory, researchers at Duke University's Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. view more (2006-05-26)
Reversing and accelerating the speed of light
Physicist Costas Soukoulis and his research group at the U.S. Department of Energy's Ames Laboratory on the Iowa State University campus are having the time of their lives making light travel backwards at negative speeds that appear faster than the speed of light. view more (2006-07-24)
Promising new metamaterial could transform ultrasound imaging
Using the same principles that help create a guitar's complex tones, researchers at the University of California, Berkeley, have developed a new material that holds promise for revolutionizing the field of ultrasound imaging. view more (2006-06-01)
Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. view more (2007-10-15)
'T-ray' devices with perfect imaging abilities move a step closer
A team of American and British scientists has demonstrated an artificially made material that can provide a magnetic response to Terahertz frequency radiation, bringing the realisation and development of novel 'T-ray' devices a step closer. The advance, reported in the journal Science today (5 March), suggests many applications in biological and... view more... (2004-03-04)
Engineers create 'optical cloaking' design for invisibility
Researchers using nanotechnology have taken a step toward creating an "optical cloaking" device that could render objects invisible by guiding light around anything placed inside this "cloak." view more (2007-04-03)
Light at the speed of a bicycle and much more
The speed of light, 300 million metres per second, was long thought an immutable constant and has defined our understanding of matter and energy but recent research in the area of optics and photonics is proving that we can manipulate light to some ingenious and hugely lucrative ends. view more (2009-09-09)
New research field promises radical advances in optical technologies
A new research field called transformation optics may usher in a host of radical advances including a cloak of invisibility and ultra-powerful microscopes and computers by harnessing nanotechnology and "metamaterials." view more (2008-10-17)
Invisibility undone
Harry Potter beware! A team of Chinese scientists has developed a way to unmask your invisibility cloak. According to a new paper in the latest issue of Optics Express, the Optical Society's (OSA) open-access journal, certain materials underneath an invisibility cloak would allow invisible objects be seen again. view more (2008-09-03)
First acoustic metamaterial 'superlens' created by U. of I. researchers
A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology. view more (2009-06-25)
First tunable, 'noiseless' amplifier may boost quantum computing, communications
