New ‘Invisibility Cloak’ Created At Duke University

January 16, 2009

North Carolina (ChattahBox) – The idea of an invisibility cloak, especially being used by the military, in not a new concept. However, new research being done by Duke University shows that the final product may be closer then ever.

Using a material they are calling ‘metamaterial’, this ultra thin type of fiberglass has been successfully used to control light, allowing an object to disappear, or at least appear to.

The scientists have named this invention the ‘broadband ground-plane cloak’, and it’s ability to capture microwave signals, twisting them, and sending them back, has made it the most exciting discovery in cloaking technology in a long time.

“The new device can cloak a much wider spectrum of waves – nearly limitless – and will scale far more easily to infra-red and visible light,” David Smith, a researcher who has worked on similar projects, releasing his own version of an invisibility cloak in 2006, as a prototype for the military, commented on the success.

“The approach we used should help us improve our abilities to cloak different types of waves.”

The theory behind the cloaking device is that is would allow an object to reflect light in a way that shows what is behind it, making it seem as though nothing is there.

But whatever implications this has for the military, it has been warned that it won’t be something available for civilian use, at least not in the foreseeable future.

“It’s not going to be something you could buy your kid for Christmas,” Professor Si John Pendry, in the Imperial College, London, told reporters.

    I loved the final commment..
    “It’s not going to be something you could buy your kid for Christmas”.

    How silly, of course it will be and it will be one of the things parents of the next generation are tormented by as their children disappear from sight more effectively than they do now.

    We live in an age where sciences secrets are mass produced in ways never conceived of by the scientific community – this cloaking device wont be any different.

    see ya
