A cloak of invisibility may be common in science fiction but it is not so easy in the real world. New research suggests such a device may be moving closer to reality.
Scientists said on Thursday (September 17) they have successfully tested an ultra-thin invisibility cloak made of microscopic rectangular gold blocks that, like skin, conform to the shape of an object and can render it undetectable with visible light.
The researchers said while their experiments involved cloaking a miniscule object they believe the technology could be made to conceal larger objects, with military and other possible applications.
The cloak, 80 nanometers in thickness, was wrapped around a three-dimensional object shaped with bumps and dents. The cloak’s surface rerouted light waves scattered from the object to make it invisible to optical detection.
What if you had a holster that was made with a cloak of invisibility? You could have the comfort and access of open carry with the discreetness of concealed carry.
