SCIENCE - New metamaterial lens focuses radio waves: Device could improve satellite and molecular imaging

In many respects, metamaterials are supernatural. These manmade materials, with their intricately designed structures, bend electromagnetic waves in ways that are impossible for materials found in nature. Scientists are investigating metamaterials for their potential to engineer invisibility cloaks—materials that refract light to hide an object in plain sight—and "super lenses," which focus light beyond the range of optical microscopes to image objects at nanoscale detail.
