How To See Through an Invisibility Cloak

Posted by timothy on from the very-zen dept.

AMESN writes "Ways to bend light around objects and render them invisible are becoming a major field of scientific study and gaining ground. While no actual invisibility cloak exists yet, researchers are also theorizing on how to beat the perfect cloak."

    And not even that. You just need to transfer the light after it has hit the person and is going back. So instead of catching the light ray when it hits the invisibility cloak, you catch it when it's leaving the invisibility cloak and transfer on the other side.

    RTA. It has a long description of John Pendry and how famous he is for using negative index of refraction for cloaking. If that's impossible his cloak won't come close to work if it is ever built. Another important point - no one discusses that the experiments in cloaking and negative index of refraction have been minimal, and no real successes. Two experiments, one at Berkeley, and one at Toronto (microwave) that are possible of being interpreted as something other than nior anyway. People in the article talk about it likes its been done. It hasn't, theoretically or experimentally.
