With the emergence of metamaterials and transformation optics in the past few years, invisibility has become a scientific possibility that has attracted sustainable research interest. Recently, a review paper, entitled "Invisibility cloak from forward design to inverse design", published in SCIENCE CHINA Information Sciences, 2013, Vol. 56, reviewed design methodologies and experimental developments of the invisibility cloak from a practical perspective. The recent transition from a forward...

An Ultra Secure Optical Communications Network With Temporal Cloaking
2013-06-06 10:07:26

redOrbit Staff & Wire Reports - Your Universe Online Researchers at Purdue University have demonstrated a temporal cloaking device for optical communications that bends light to create holes in time, something that could have important implications for sending secret messages over fiber optic cables or thwarting would-be eavesdroppers. "More work has to be done before this approach finds practical application, but it does use technology that could integrate smoothly into the...

“This may be difficult to imagine, but SEO is still alive and well one year after Google´s Penguin algorithm update and two years after the Panda update. However, there is one thing for certain, I will never look at those cute and lovable animals in the same way”, stated Peter Rossi founder of ProfitSearch who commented on the Google´s Panda and Penguin updates. New York, New Jersey, Wilmington DE, Chicago. San Fransosco (PRWEB) May 31, 2013 Before one can assess their...

'Invisibility' Cloak For Buildings No Longer Just Sci-Fi
2012-02-14 14:15:49

A group of British researchers has been hard at work attempting to bring a seemingly kooky, outlandish idea into the realm of the real. Their work has focused on attempting to create a proverbial invisibility cloak that would enable engineers to ℠hide´ buildings from earthquake tremors and other destructive forces. Once the exclusive territory of science-fiction, scientists have explored the theory of ℠cloaking´ in a variety of contexts and fields in recent years. One...

University of Texas at Austin researchers have cloaked a three-dimensional object standing in free space for the first time. The researchers used a method known as plasmonic cloaking to hide a 7-inch cylindrical tube from microwaves.  During the study, they were able to show how ordinary objects can be cloaked in their natural environment in all directions and from all vantage points. When using the plasmonic cloaking method, light strikes an object, and rebounds off its surface...

Optical cloaking devices that enable light to gracefully slip around a solid object were once strictly in the realm of science fiction. Today they have emerged as an exciting area of study, at least on microscopic scales. A new twist on this intriguing technology can now be "seen" in the field of acoustics. A team of researchers from the Universitat Politecnica de Valencia and the Universidad de Valencia have created a prototype of an acoustic cloak by using a 2-D mathematical model. Unlike...

Researchers in Britain and Denmark have unveiled an "Ëœinvisibility cloak' that uses a common crystalline material known as calcite, which works by sending its two "polarizations" of light in different directions. Cloaking involves guiding light waves in such a way that waves from a hidden object do not reach the eye.  By using calcite, the researchers created an "Ëœinvisibility cloak' that hid a small (inch-size), three-dimensional object.  However, the size of...

 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 from tsunamis."We have shown that it is numerically possible to cloak objects of any shape that lie outside the cloaking devices, not just from...

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 the year by Science magazine in 2006, cloaking involves making an object invisible or undetectable to electromagnetic waves. A paper published in the...
