Posted by in category: futurism

The concept of an invisibility cloak sounds like pure science fiction, but hiding something from view is theoretically possible, and in some very-controlled cases it’s experimentally possible too. Now, researchers have developed a new device that works in a completely different way to existing cloaking technology, neatly sidestepping some past issues and potentially helping to hide everyday objects under everyday conditions.

We see objects because light bounces off them in a particular way before landing on your retinas, and they get their colors by reflecting more light of that particular color. The basic concept of cloaking objects involves finding ways to disrupt that process and build them into devices or metamaterials.
