The New Black

Look out, Harry Potter: researchers have advanced the study of cloaking—rendering objects invisible by forcing light waves to act as if the objects weren't there.

In a paper published in this week's Science, a team from Duke University and Southeast University in Nanjing, China, reports a new and improved cloak that can conceal a bump—and anything hidden beneath—on a flat surface. Both the surface and the bump (visible at the far left in the photo) must be reflective, however. The new setup is upgraded to function for a relatively broad spectrum of light, whereas previous models had very narrow operational regimes.

This cloak, like its predecessors from the group of David Smith, an electrical and computer engineering professor at Duke, is built from metamaterials—novel composite structures designed to make light work in unusual ways.

Although the new cloak represents a step forward, even this "broadband" model is still a long way from rerouting visible light. The wavelengths of the microwave radiation regime in which the cloak works are tens of thousands of times longer than those of visible light.

genius did you come up with this or did you get it from another forum? i need to know. PM if neccessary.

awesome.

I'll believe it when I see it (or don't see it, snicker). We were supposed to have hovercraft cars by now, and that didn't happen...

I'm sure I could find a use for one of those.

I wish someone would hurry up and get working on transporter beams (Star Trek). I want to go to Europe, but hate the idea of a 10 hour plane ride.

Transit in my city is sloooow. Where's our Jetsons jetpacks?
