The First Working “Invisibility Cloak” (+VIDEO)
A team led by scientists at Duke University’s Pratt School of Engineering has made the first working “invisibility cloak.” This garment can fully hide a small object, invisible to the naked eye, in wavelengths longer than what the eye can see, such as infrared, microwaves and radio. It deflects microwave beams so they flow around a “hidden” object inside with little distortion, making it seem almost as if nothing were there at all. The cloak features a row-by-row design of fiberglass etched with copper and copper strips. This design is an improved prototype of 2006 that, due to a less precise fabrication process, continued to reflect light around the edges of the concealed object, leaving it partially exposed. The weakness of the current design is that it works from one direction and if the object is viewed from side, it would be visible. The team is optimistic to use the results of the research will help them to create a three-dimensional illusion.
