Cloaking Device a Reality? Only if You're Very Small

The cloak itself is quite small, a mere 10 micrometers in width (PDF). The structure of the device is a simple thin layer of acrylic plastic with a pattern of concentric, two-dimensional rings atop a gold film. The ring pattern creates a negative refraction effect on visible light striking it, bending the plasmons around the object. While the light appears to have passed straight through the material, it has in fact gone around it.
