An invisibility
cloak developed by David Smith's laboratory at Duke University. Placing
an object in the center makes it invisible to microwave radiation. The
cloaking material splits the oncoming microwaves, guiding them around
the object and recombining them on the other side. Since the microwaves
do not interact with the cloaked object, an observer on the right or
left of the object would not notice it was hidden.
