Researchers at the University of California, Berkeley, reporting that they were able to render a three-dimensional object completely invisible for the first time. Previously, scientists could only cloak super thin, 2D object. Harry Potter is not happy right now. It’s going to be way harder to save the wizardry world from certain doom if everybody has got their own invisibility cloak. Jeez, bandwagon jumpers, much?
Here’s what the AP has to say:
People can see objects because they scatter the light that strikes them, reflecting some of it back to the eye. Cloaking uses materials, known as metamaterials, to deflect radar, light or other waves around an object, like water flowing around a smooth rock in a stream.
