Cloaking theorically demonstrated

Thanks to the "anomalous localised resonance" effect.

By using a material called superlens, Nicolae Nicorovici and Graeme Milton could make objects appear to vanish.

So far, they have been able to make disappear small objects, small as dust.

The technique is based on light wave resonance instead of sound wave resonance (used to detect ship with radars). The superlens material would absorb the light from a certain range of frenquencies, which would sometimes make the object partially disappear.

However, the authors have so far only done the maths to verify that the concept could work. Building such a device would undoubtedly pose a significant challenge.
