Scientists manage to \’cloak\’ a 3-D object from all angles

Researchers have \”cloaked\” a three-dimensional object, making it invisible from all angles, for the first time.

However, the demonstration works only for waves in the microwave region of the electromagnetic spectrum.

It uses a shell of what are known as plasmonic materials; they present a \”photo negative\” of the object being cloaked, effectively cancelling it out.
