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...

Chinese physicists may not yet be able to move between parallel universes or become invisible, but they've created the first tunable electromagnetic gateway. Researchers at the Hong Kong University of Science and Technology and Fudan University in Shanghai said their concept of a gateway that can block electromagnetic waves, but that allows the passage of other entities resembles hidden portals or invisibility cloaks mentioned in works of science fiction or fantasy, such as the Harry Potter...

Schools and hospitals could one day be protected from feeling the effects of an earthquake. CNRS researchers at the Institute Fresnel in Marseille (1) have come up with a system that could protect buildings from the most destructive seismic waves. Based on mathematical models, such an 'invisibility cloak' could find applications ranging from the automobile and aviation industries to earthquake protection. The paper appears in the journal Physical Review Letters dated 10 July 2009.The...

 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.As directed by the researchers' novel device, these beams continue to behave as if traveling in a straight line. In one computer simulation, Assistant Professor of Physics Willie J. Padilla and researcher Nathan Landy revealed the...

Research at the University of Liverpool has shown it is possible to develop an "Ëœinvisibility cloak' to protect buildings from earthquakes. The seismic waves produced by earthquakes include body waves which travel through the earth and surface waves which travel across it. The new technology controls the path of surface waves which are the most damaging and responsible for much of the destruction which follows earthquakes. The technology involves the use of concentric rings of...

Physicists at UAB describe how to make objects invisible at very low frequency light with magnetic field shielding dc metamaterialsA 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. The device, which up to date has only been studied in theoretical...

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."Whereas previous cloaking designs have used exotic "metamaterials," which require complex nanofabrication, the new design is a far simpler device based on a "tapered optical waveguide," said Vladimir Shalaev, Purdue...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
