CLOAKING DEVICES INCH CLOSER TO REALITY...

Spaceship (SPL)

From the BBC comes this story of two scientists working to make "Star Trek" - style cloaking devices a reality...
The cloaking devices that are used to render spacecraft invisible in Star Trek might just work in reality, two mathematicians have claimed.

They have outlined their concept in a research paper published in one of the UK Royal Society's scientific journals.

Nicolae Nicorovici and Graeme Milton propose that placing certain objects close to a material called a superlens could make them appear to vanish.

It would rely on an effect known as "anomalous localised resonance".

[...]

Cloaking devices are a form of stealth technology much favoured by Star Trek baddies such as the Romulans and Klingons.

The complex mathematical phenomenon outlined by Milton and Nicorovici closes the gap a little between science fiction and fact.

The phenomenon is analogous to a tuning fork (which rings with a single sound frequency) being placed next to a wine glass. The wine glass will start to ring with the same frequency; it resonates.

The cloaking effect would exploit a resonance with light waves rather than sound waves.

Cool!
