The first three-dimensional visible light invisibility cloak
2014-09-29 17:07:11| Extremetech
Researchers at the University of Rochester are reporting that they've built the first invisibility cloak that works in three dimensions, viewed from a range of angles, across the full spectral range of visible light. As you can see in the photo above, and in the video below, the invisibility effect is rather effective -- and, importantly, it creates very little "telltale" distortion that usually accompanies such early attempts at cloaking (the grid lines are perfectly straight and not magnified/minimized). Best of all, though: You can make this particular kind of invisibility cloak yourself!
