Physicists Build “Ghost” Cloaking Device

[Still Waters]

Illusion cloaks that make one object look like another are a fascinating type of invisibility device. The general idea is that such a device would make an apple look like a banana or a fighter plane look like an airliner. Clearly this would have important applications.

Today, Tie Jun Cui and buddies at Southeast University in Nanjing, China, say they’ve designed and built a practical alternative to illusion cloaks, which they call a “ghost cloak”.
