The post talked about a theoretical cloak. It didn't yet exist.
Now it does.
Duke University took the wraps off invisibility cloaks Thursday (Oct. 19), announcing that researchers managed to cloak a five-inch-square area from microwave detection.
The cloaking technique worked by using a metamaterial as a shield to redirect microwaves around the cloak. Duke researchers said they hope to create invisibility cloaks for other types of electromagnetic radiation, causing even visible light to flow around shielded regions.
Hmm. I wonder if I can retrofit the trusty Intrepid with one of those and dump my radar detector?
