Harry Potter’s Cloak of Invisibility that hid him from Muggles and wizards alike may one day be a real thing.
Engineers at Duke University have developed the first functional ‘cloaking’ device, which is able to guide the electromagnetic waves around an object and then re-emerge on the other side, effectively hiding the object.
Clothes that render the wearer invisible have existed in mythology long before J K Rowling wrote Harry Potter. Greek god of the underworld Hades was given an invisibility helmet by Cyclopes to help him in the battle against the Titans.
The electrical engineers first created a functional cloaking device in 2006 but it was not perfected. The new design fixes the problems from the original device.
The goal of this type of research involves “taming light”, with the team creating meta-materials, which are man-made objects that have properties absent in natural ones.
