Researchers at the University of St. Andrews have devised a material, comprised solely of tiny atoms that can interact with light, which brings the possible invention of an invisibility cloak one step closer to becoming a reality. Writing in the Thursday edition of the New Journal of Physics, Dr. Andrea Di Falco and her colleagues describe Metaflex, a flexible metamaterial that interrupts the flow of light rays and forces them to flow around the object which it covers--"rather like water that...

Researchers at the Tufts University School of Engineering and Boston University have fabricated and characterized the first large area metamaterial structures patterned on implantable, bio-compatible silk substrates.The research, reported online July 21, 2010, in the journal Advanced Materials, provides a promising path towards the development of a new class of metamaterial-inspired implantable biosensors and biodetectors.  Metamaterials are artificial electromagnetic composites,...

Researchers have overcome a fundamental obstacle in using new "metamaterials" for radical advances in optical technologies, including ultra-powerful microscopes and computers and a possible invisibility cloak. The metamaterials have been plagued by a major limitation: too much light is "lost," or absorbed by metals such as silver and gold contained in the metamaterials, making them impractical for optical devices. However, a Purdue University team has solved this hurdle, culminating three...

An invisibility cloak made of glass From Tolkien's ring of power in The Lord of the Rings to Star Trek's Romulans, who could make their warships disappear from view, from Harry Potter's magical cloak to the garment that makes players vanish in the video game classic "Dungeons and Dragons, the power to turn someone or something invisible fascinates mankind. But who ever thought that a scientist at Michigan Technological University would be serious about building a working invisibility cloak?...

Powerful new microscopes able to resolve DNA molecules with visible light, superfast computers that use light rather than electronic signals to process information, and Harry Potteresque invisibility cloaks are just some of the many thrilling promises of transformation optics. In this burgeoning field of science, light waves can be controlled at all lengths of scale through the unique structuring of metamaterials, composites typically made from metals and dielectrics "“ insulators that...

Scalable devices inspired by nature exhibit customizable optical properties suitable for applications ranging from highly sensitive sensors and detectors to invisibility cloaks Imagine creating novel devices with amazing and exotic optical properties not found in Nature"”by simply evaporating a droplet of particles on a surface. By chemically building clusters of nanospheres from a liquid, a team of Harvard researchers, in collaboration with scientists at Rice University, the University...

Researchers have successfully rendered a minute bump on a gold surface invisible, using special masking technology that could someday bring true invisibility cloaks from the realms of science fiction and fantasy into reality. Scientists from Karlsruhe Institute of Technology in Germany and Imperial College London "used photonic crystals with a structure that looks like piles of wood to make an invisibility device, or cloak," Reuters reporter Kate Kelland wrote in a March 18 article. "The...

Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. A team of researchers at the Karlsruhe Institute of Technology in Germany has created a new visualization tool that can render a room containing such an object, showing the visual effects of such a cloaking mechanism and its imperfections. To illustrate their new tool, the researchers have published an article in the latest issue 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...

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.The work, 'A simple route to a tunable electromagnetic gateway' is a further advance in the study of metamaterials, published today, Thursday, 14 August, in New Journal of Physics (co-owned by the Institute of Physics and...
