Scientists Create Cloak of Invisibility

Another news item from Wanttoknow.info(for the full ABC news article click here): "Scientists are boldly going where only fiction has gone before to develop a Cloak of Invisibility. It isn't quite ready to hide a Romulan space ship from Capt. James T. Kirk or to disguise Harry Potter, but it is a significant start and could show the way to more sophisticated designs. In this first successful experiment, researchers from the United States and England were able to cloak a copper cylinder. It's like a mirage, where heat causes the bending of light rays and cloaks the road ahead behind an image of the sky. "We have built an artificial mirage that can hide something from would-be observers in any direction," said cloak designer David Schurig, a research associate in Duke University's electrical and computer engineering department. Cloaking used special materials to deflect radar or light or other waves around an object, like water flowing around a smooth rock in a stream. The new work points the way for an improvd version that could hide people and objects from visible light. Conceptually, the chance of adapting the concept to visible light is good, Schurig said in a telephone interview. But, he added, "From an engineering point of view it is very challenging." The cloaking of a cylinder from microwaves comes just five months after Schurig and colleagues published their theory that it should be possible. In an ideal situation, the cloak and the item it is hiding would be invisible. An observer would see whatever is beyond them, with no evidence the cloaked item exists.

Note: Remember that technologies developed in top-secret military, intelligence, and other government projects are generally at the very least 10 years in advance of anything being developed in the public domain."
