Cloaking Device
Granted it only works for mono-cromatic(one color) specks of dust but it is still cool. My hope is to build this technology into a ring with which I can rule ALL of MIDDLE EARTH booo haa haa haa haa haaa haaaaaa !
OK over the top but this is still cool. But the article does not say that the clocked object will be transparent. Just invisible. Makes me think it will be like is it is covered in a strange dark shadow. And will only work for object s of one color and of certain shapes. So obviously there is work to be done.
Anyway when are we gonna see flying cars ? Is Anybody working on that ?
Physicists Nicolae Nicorovici from the University of Sydney, Australia, and Graeme Milton, from the University of Utah, have proposed that devices called superlenses could be used to create a type of cloaking device. Using a principle called “anomalous localized resonance,” superlenses placed very close to a small object could mask its reflected light waves by resonating at the same frequency, much like how noise-canceling headphones mask sound waves by creating a sound that is at the same frequency but inverted in phase.

Professor Sir John Pendry, of Imperial College London, who helped pioneer superlenses, said: “If the speck of dust is close enough it induces a very aggressive response in the cloaking material which essentially acts back on the speck of dust and forces it to stop shining.
“Even though light is hitting the speck of dust, scattering of the light is prevented by the cloak which is in close proximity,” he told the BBC News website.
