What invisible objects will actually look like

By - November 12, 2009 3 Pictures
Over the last few years we’ve covered the development of “invisibility cloaks” using metamaterials – man-made structured composite materials exhibiting optical properties not found in nature that can guide light to achieve cloaking and other optical effects. In 2006, scientists at Duke University demonstrated in the laboratory that an object made of metamaterials can be partially invisible to particular wavelengths of light - not visible light, but rather microwaves. A few groups have even managed to achieve a microscopically-sized carpet-cloak. Now researchers have developed software that can show what such a cloaked object will actually look like. Read More

Stealth wind turbines developed to avoid radar confusion

By - November 3, 2009
Plans for the installation of wind farms the world over are being delayed or abandoned due to objections from the aviation community or air defense interests. The problem is that when it comes to low flying aircraft or wind turbines, conventional radar has a bit of an identity crisis - not being able to tell the difference. Recent tests in the UK of "stealth" turbine technology could provide a solution. Read More

Invisible Flash sheds new light on photography in the dark

By - August 6, 2009 4 Pictures
As technology becomes available to help those wishing to avoid the annoying flash photography of the paparazzi get some payback, researchers Dilip Krishnan and Rob Fergus from New York University have developed a system for taking dazzle-free photos in poor lighting conditions which could result in celebs not even knowing they're being photographed. Named dark light flash photography by its creators, the system uses light waves beyond our visible range and special software and algorithms to produce photos comparable in quality to a long exposure shot.

Bringing sight to the invisible

By - March 17, 2009
Invisibility has been a staple of science fiction, (and my own personal fantasies), for decades and in recent years we’ve watched as fiction edges ever closer to reality through the use of metamaterials. The problem with most of the devices currently being researched however, is that since they totally encompass the object being rendered invisible, they are also rendered blind as well, which kind of defeats the purpose. But a team from Hong Kong’s University of Science and Technology believes they have come up with an answer to this problem and that it is indeed possible to create a cloaking device that would be able to render an object invisible without encompassing it.

Metamaterials could create sonar-invisible vessels

By - June 16, 2008
June 16, 2008 Research into the cloaking properties of “left handed” metamaterials is continuing, with the latest news coming from scientists at the Polytechnic University of Valencia who have proven that these man-made substance can make objects impervious to sound waves. A proposed "acoustic cloak" would use sonic crystals, a class of metamaterial, to bend sound waves around an object, and could be used to render vessels Sonar-invisible... perhaps even bring to life that staple of spy technology: the Cone of Silence.

Sight unseen: metamaterials could be used to create invisible ships

By - March 1, 2008
March 2, 2008 Like a lot of emerging science, the study of metamaterials is both amazingly cool and nearly impossible to understand without an advanced degree in physics or a long night on Wikipedia. It’s made Gizmag headlines before, with researchers claiming its unique structure, which has a negative refractive index, could be used to render objects invisible to the naked eye. Now scientists at Britannia Royal Navy College are working on a plan to use it to create the ultimate stealth vessel, according to a report in this month's edition of Physics World. Read More

FlatWire Ready offers invisible power

By - May 31, 2007
June 1, 2007 With wireless technologies being incorporated into many new products, the scope for interior designers to create a new and uncluttered look has never been greater – and we suspect it will be some time yet until we have commercially available wireless power. Which is why we’re so bullish on this product. Since its first patents were filed in 1995, FlatWire Ready technology has been winning awards and converts for its unique approach to electrical wiring. The technology is now available for low voltage lighting, audio, video, voice and data and considerable attention has been paid to the development of installation accessories that make it easy for even a novice DIYer to install in minutes in four easy steps - Map it, Stick It, Click It, and Make it Disappear.
