It’s like a mirage, where heat causes the bending of light rays and cloaks the road ahead behind an image of the sky.

“We have built an artificial mirage that can hide something from would-be observers in any direction,” said cloak designer David Schurig, a research associate in Duke University’s electrical and computer engineering department.
