"It sounds like something out of a science fiction movie: In April, China is said to have tested an invisibility cloak that would allow ordinary fighter jets to suddenly vanish from radar screens.
This advancement, which could prove to be a critical intelligence breakthrough, is one that American officials fear China may have gained in part from a Chinese researcher who roused suspicions while working on a similar technology at a Duke University laboratory in 2008. The researcher, who was investigated by the F.B.I. but never charged with a crime, ultimately returned to China, became a billionaire and opened a thriving research institute that worked on some projects related to those he studied at Duke."
