Yeah, but can you heat it up? Or maybe if you fly slow enough, it won't so who cares?Chinese scientists announced they’ve invented a new kind of coating for aircraft and other weapons that’s virtually undetectable by radar.
This new, lab-made "metamaterial," in essence a very fine mesh with microscopic etchings, could shrink the radar signature of a fighter jet, warship, or missile by a thousand times, claimed the scientists at the Chengdu-based Institute of Optics and Electronics, part of the Chinese Academy of Sciences.
