Perfect image without metamaterials ... and a reprieve for silicon chips
Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility. view more (2009-09-29)
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)
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)
A new cloaking method
University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures... view more... (2009-08-17)
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)
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)
Stripping leukemia-initiating cells of their 'invisibility cloak'
Two new studies reveal a way to increase the body's appetite for gobbling up the cancer stem cells responsible for acute myeloid leukemia (AML), a form of cancer with a particularly poor survival rate. view more (2009-07-24)
'Invisibility cloak' could protect against earthquakes
Research at the University of Liverpool has shown it is possible to develop an 'invisibility cloak' to protect buildings from earthquakes. view more (2009-07-21)
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)
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)
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)
Blurring the Line Between Magic and Science: Berkeley Researchers Create an 'Invisibility Cloak'
The great science fiction writer Arthur C. Clarke famously noted the similarities between advanced technology and magic. This summer on the big screen, the young wizard Harry Potter will once again don his magic invisibility cloak and disappear. view more (2009-05-04)
HIV pays a price for invisibility
Mutations that help HIV hide from the immune system undermine the virus's ability to replicate, show an international team of researchers in the April 13 issue of the Journal of Experimental Medicine. view more (2009-04-13)
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)
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...

Now you see it, now you don't: MBL scientists unraveling the mystery of camouflage
At Hogwarts, Harry Potter uses an invisibility cloak to hide from his enemies. In nature, animals like cuttlefish and chameleons use the awe-inspiring tricks of camouflage to hide from theirs. view more (2009-01-16)
Using invisibility to increase visibility
Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye. view more (2008-12-01)
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)
