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)

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... 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)

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)

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)

'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)

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... view more (2008-08-11)

'Electromagnetic Wormhole' Possible with Invisibility Technology
The team of mathematicians that first created the mathematics behind the "invisibility cloak" announced by physicists last October has now shown that the same technology could be used to generate an "electromagnetic wormhole."   view more (2007-10-15)

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)

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)

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)

'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... view more (2004-03-04)

Purdue 'metamaterial' could lead to better optics, communications
Engineers at Purdue University are the first researchers to create a material that has a "negative index of refraction" in the wavelength of light used for telecommunications, a step that could lead to better communications and imaging technologies.   view more (2005-12-01)
