The researchers from the Karlsruhe Institute of Technology have come with a 3D cloak that can lead to invisibility. They managed to put out of sight a bump on a gold plate with the help of "metamaterials", making the plate look flat when seen via infra-red light.

The research was led by Tolga Ergin and it will today be published in the journal of Science.

"You could imagine you have a flat gold mirror and you could put an object on that mirror", he said.

The metamaterials are designed to bounce the light away from the object in such a way that it bends around the object making in invisible.

Dr. David Powell from the Centre for Linear Physics at the Australian National University appreciated the use of metamaterials for the purpose.

He added that metamaterials come with the liberty and capability of bending the light in a desired way.

It is the first time these metamaterials have been used to hide a 3D object in infrared light.

Mr. Ergin explained that prior to the latest move; the scientists had been using different wavelengths like microwaves, which cannot be detected by the human eye, for hiding the objects.
