3D invisibility cloak fashioned out of metamaterials
March 19, 2010

Those HDTV manufacturers did tell us that 3D was going to be everywhere this year, didn't they? Keeping up with the times, scientists investigating potential methods for rendering physical objects invisible to the human eye have now moved to the full three-dimensional realm. The Karlsruhe Institute of Technology has developed a photonic metamaterial that can make things disappear when viewed from all angles, advancing from previous light refraction methods that only worked in 2D. It sounds similar to what Berkeley researchers developed not too long ago, and just like Berkeley's findings, this is a method that's still at a very early stage of development and can only cover one micrometer-tall bumps. Theoretically unlimited, the so-called carpet cloak could eventually be expanded to "hide a house," but then who's to say we'll even be living in houses by that time?
