Advancements in fabrication technologies may lead to superlenses and other designer optical materials, according to an Iowa State University and Ames Laboratory physicist. In an article titled "Improving Metamaterials" published in the Perspectives section of the Dec. 17 issue of the journal Science, Costas Soukoulis and Martin Wegener write about the man-made materials designed to deliver certain properties not found in nature. Soukoulis is an Iowa State University Distinguished Professor...

Experimental verification of reversed Cerenkov radiation in left-handed metamaterial A team of physicists has directly observed a reverse shock wave of light in a specially tailored structure known as a left-handed metamaterial. Although it was first predicted over forty years ago, this is the first unambiguous experimental demonstration of the effect. The research is reported in Physical Review Letters and highlighted with a Viewpoint in the November 2 issue of Physics. Light moving in a...

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...

Resonators couple individually to electric and magnetic fields to absorb all incident radiation CHESTNUT HILL, MA "“ A team of scientists from Boston College and Duke University has developed a highly-engineered metamaterial capable of absorbing all of the light that strikes it "“ to a scientific standard of perfection "“ they report in the latest edition of Physical Review Letters. The team designed and engineered a metamaterial that uses tiny geometric surface features to...
