Via KurzweilAI.net — I’ve done plenty of blogging on invisibility cloaking technology, and here’s the lastest. I think this tech is very cool and I hate to throw any cold water on the latest news, but I’d be more impressed with seeing an actual effective working model of a simple cloaking device before getting to wild with advanced varients like those described below.
Modified invisibility cloak could make the ultimate illusion New Scientist Tech, July 7, 2009 An illusion device using metamaterials that makes one object look like another could one day be used to camouflage military planes or create “holes” in solid walls.
To make a cup look like a spoon, for example, light first strikes the cup and is distorted. It then passes through a complementary metamaterial which cancels out the distortions to make the cup seem invisible. The light then moves into a region of the metamaterial that creates a distortion as if a spoon were present. The result is that an observer looking at the cup through the metamaterial would see a spoon.
