When someone claims he or she has seen a ghost, the phenomenon may be caused by an optical illusion happening through a wild stroke of nature. But the actual engineering of such a phenomenon is the holy grail of researchers in the field of optical illusions, electromagnetic, and radar detection — not only because of the thrill and excitement of being able to create a “ghost” but because of the implications it will have in science and applications….
