In this image released to Reuters August 12, 2008 by the University of California, Berkeley, a scanning electron microscope image of the first "fishnet" metamaterial (L) that may allow objects to be "cloaked" is shown, developed by UC Berkeley researchers. Scientists have created two new types of materials that can bend light the wrong way, creating the first step toward an invisibility cloaking device. Two teams were working separately under the direction of Xiang Zhang of the Nanoscale Science and Engineering Center at the University of California, Berkeley with U.S. government funding. One team reported its findings in the journal Science and the other in the journal Nature. REUTERS/Jason Valentine/UC Berkeley/Handout (UNITED STATES). FOR EDITORIAL USE ONLY.
