Two mathematicians, Graeme Milton from Utah University and Nicolae-Alexandru Nicorovici from Sydney University of Technology have proposed calculations for a real cloaking device.

The calculations require a new material they refer to as a "superlens". Objects that are placed close to the superlens appear invisible. The superlens is composed of newly found materials that cause light to behave abnormally. Instead of making light bend as it passes through, the superlens causes light to effectively travel backward.

Currently the proposal is simply mathematical calculations and no actual prototype has yet been developed.
