A research team has created an easy-to-produce material that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This break through can benefit high-speed communications, medical diagnostics and detection of terrorist and many other areas. threats.
the material is new class called "metamaterials," which are made out of traditional substances, such as metals or semiconductors, arranged in very small alternating patterns that modify their collective properties. This approach enables metamaterials to manipulate light in ways that cannot be accomplished by normal materials.
Previous metamaterials were two-dimensional arrangements of metals, which limited their usefulness. but to be useful the materila has to be three-dimensional said electrical engineering professor Clair Gmachl.
