NSA Will Use This

In diversionary cloaking, EM waves are scooted around an object (for illustration, see the Skilluminati article, Dreaming 5GW: Invisible War) The disadvantage here however is that the object is in a sense hermetically sealed from the environment, rendered incommunicado by its cloak.

A new method avoids this disadvantage by scattering EM waves in a manner similar to noise-cancellation devices. Says Nader Engheta in Science News, Cloaked Eye Still Sees:

“We are asking the question, ‘Is it possible to put a layer around an object such that when a wave hits the object, the wave scatters less?’ If the cloak is designed properly, the effect is reduced, like a cancelling effect... It puts in balance the object and the cloak.”

Hence, NSA listening posts will go undetected... And bug-detection manufacturers would be wise now to invest in more R&D.
