This discovery brings us one step closer to Harry Potter’s invisibility cloak

This discovery brings us one step closer to Harry Potter’s invisibility cloak

September 28, 2014

It’s like a very small invisibility cloak made of glass. Researchers at the University of Rochester seem to be taking the words of science fiction writer Arthur C. Clarke’s to heart: “any sufficiently advanced technology is indistinguishable from magic.”

‘Cloaking’ device uses ordinary lenses to hide objects across range of angles

Scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed by physics professor John Howell and graduate student Joseph Choi, not only overcomes some limitations of previous devices, but uses inexpensive, readily available materials in a new way. “This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking,” said Choi.

Physicists have figured out the optical parameters for a magic trick they characterize as a kind of “invisibility cloak” — and unlike most magicians, they’re only too willing to show you how it’s done. “We just figured a very simple way of doing that can just be using standard lenses, and things that we normally find in the lab,” physics professor John Howell said in a video explaining the setup.

With the help of his 14 year-old son, Benjamin, John Howell built three simple but surprisingly effective optical cloaking devices with inexpensive, off-the-shelf materials.
