"We've demonstrated a different way of doing it," said Eleftheriades. "It's very simple: instead of surrounding what you're trying to cloak with a thick metamaterial shell, we surround it with one layer of tiny antennas, and this layer radiates back a field that cancels the reflections from the object."

Their demonstration used one loop of antennas to cloak a smaller object, but the researchers reckon that the system could be scaled up using additional loops to cover much larger things – like military tanks for example. The system also has to be manually tuned to the electromagnetic frequency it needs to cancel out, but the antennas could work as sensors as well in the future, adjusting to different waves in real-time – much like noise-cancelling headphones.
