Scientists find new role for the swastika
Just a month after a call for a European-wide ban of the swastika, scientists have found that the symbol has new applications in optical communications and could have a role in quantum cryptography. view more (2005-02-23)
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)
Metamaterials with new electromagnetic properties
The development of new types of artificial materials, known as "metamaterials" and with electromagnetic properties not found in nature, is the aim of the Metamorphose Excellence European Network, of which the Public University of Navarre forms part, together with twenty-one other research institutions from 13 European countries. view more (2004-03-25)
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)
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)
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)
COES professor's 'metamaterials' research lands cover of international journal
Dr. Dentcho Genov, an assistant professor of physics and electrical engineering at Louisiana Tech University and a Louisiana Optical Network Initiative (LONI) Institute fellow, is featured on the cover of the most recent issue of Nature Physics, one of the most respected and prestigious physics journals in the world. view more (2009-09-11)
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)
Invisibility visualized: German team unveils new software for rendering cloaked objects
Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. view more (2009-11-13)
Metamaterials four to work for visible light
For the first time ever, researchers at the U.S. Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light. view more (2007-01-05)
Scientists closer to making invisibility cloak a reality
J.K. Rowling may not have realized just how close Harry Potter's invisibility cloak was to becoming a reality when she introduced it in the first book of her best-selling fictional series in 1998. Scientists, however, have made huge strides in the past few years in the rapidly developing field of cloaking. Ranked the number five breakthrough of... view more... (2009-03-06)
New 'broadband' cloaking technology simple to manufacture
Researchers have created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in "transformation optics." view more (2009-05-21)
Next generation cloaking device demonstrated
A device that can bestow invisibility to an object by "cloaking" it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University engineers has produced a new type of cloaking device, which is significantly more sophisticated at... view more...

'Invisibility cloaks' could break sound barriers
Contrary to earlier predictions, Duke University engineers have found that a three-dimensional sound cloak is possible, at least in theory. view more (2008-01-10)
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)
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...

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)
Steps towards warship invisibility
Naval warships might look like all-powerful vessels but they are also highly vulnerable to being spotted by the enemy. view more (2008-03-03)
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)
Nanofabrication method paves way for new optical devices
