According to a BBC report Scientists have created a cloak which "rendered objects invisible under near-infrared light." Unlike previous such "cloaks", the new work does not employ metals, which introduce losses of light and result in imperfect cloaking. Because the approach can be scaled down further in size, researchers say this is a major step towards a cloak that would work for visible light. Tiny holes all over the cloak bend the light around the bump Xiang Zhang, Professor of Mechanical Engineering at the University of California, Berkeley lead one of the two teams working on this project: "Essentially, we are transforming a straight line...
