Invisibility Shields One Step Closer With New Metamaterials That Bend Light Backwards
This August 2008 article describes how "scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and ... cloaking devices that could render objects invisible to the human eye." Includes illustrations. From University of California, Berkeley, News.
