Invisibility Cloak: Not Just for Harry Potter

Share this article

Ever think that invisibility cloaks were for science fiction novels or Harry Potter? Well that may not be the case any longer. According to this article from the associated press, scientists are close to creating 'materials that could render people and objects invisible.' Researchers have been able to successfully render 'very thin two-dimensional objects' invisible. The exact findings will be released later this week by scientists from the University of California Berkeley, led by Xiang Zhang. As the article explains '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.' Funding for this project has come from the U.S. Army Research Office and the National Science Foundation's Nano-Scale Science and Engineering Center.
