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 (2008-04-15)

'T-ray' breakthrough signals next generation of security sensors
A new generation of sensors for detecting explosives and poisons could be developed following new research into a type of radiation known as T-rays, published today (Feb. 3) in Nature Photonics. (2008-02-05)

Getting light to bend backwards
While developing new lenses for next-generation sensors, researchers have crafted a layered material that causes light to refract, or bend, in a manner nature never intended. (2007-10-16)

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. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats. (2007-10-14)

'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.' (2007-10-12)

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 airplanes and submarines, appear invisible at close range. (2007-05-03)

Engineers create 'optical cloaking' design for invisibility
Researchers using nanotechnology have taken a step toward creating an (2007-04-02)

Metamaterials found to work for visible light
For the first time ever, researchers at the US Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light. Ames Laboratory senior physicist Costas Soukoulis, working with colleagues in Karlsruhe, Germany, designed a silver-based, mesh-like material that exhibits a refractive index of -0.6 at the red end of the visible spectrum. (2007-01-04)

T-ray breakthrough could make detecting disease far easier
A breakthrough in the harnessing of (2006-11-02)

First demonstration of a working invisibility cloak
A team led by scientists at Duke University's Pratt School of Engineering has demonstrated the first working (2006-10-19)

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. (2006-07-21)

Promising new metamaterial could transform ultrasound imaging
Researchers at the University of California, Berkeley, have used the principles of resonance to develop a new material that holds promise for revolutionizing the field of ultrasound imaging. This (2006-05-31)

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. Once devised, the cloak could have numerous uses, from defense applications to wireless communications, the researchers said. (2006-05-25)

Cheaper mobile phones or GPS and with enhanced performance
In his PhD thesis the Pamplona engineer, Francisco Falcone Lanas, has put forward various structures based on what are known as left-handed metamaterials -- materials that can be used to make smaller mobile phones, aerials or GPS and which have better specifications and performance. This is the first PhD thesis defended on applications of left-handed metamaterials. (2005-11-29)

Twinkle, twinkle little star, how I wonder where you are
Whether viewed dimly through the haze and lights of a city or in all their glory in a pristine wilderness, the stars that surround the Earth are magnificent, and one day Earthlings will travel to some of the new planets that astronomers are locating. However, the stars we see are not necessarily where we think they are, according to an international research team. (2004-08-04)

'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. (2004-03-04)

University of Toronto study charts new realm of physics
By constructing artificial materials that break long-standing rules of nature, a University of Toronto researcher has developed a flat lens that could significantly enhance the resolution of imaged objects. This, in turn, could lead to smaller and more effective antennas and devices for cell phones, increased space for data storage on CD-ROMs and more complex electronic circuits. (2003-03-19)

Physicists verify reversal of Snell's Law in 'left-handed' composite material
Physicists at the University of California, San Diego who last year produced a new class of composite materials believed to reverse the behavior of many fundamental electromagnetic properties associated with materials, have experimentally verified the first of these predicted reversals. (2001-04-05)
