The science of invisibility

The science of invisibility 


Refractive materials give limited control of light: we can fashion
lenses, and construct waveguides, but complete control is beyond
simple refracting materials. Ideally we might wish to channel and
direct light as we please just as we might divert the flow of a fluid.
Manipulation of Maxwell’s equation shows that we can achieve just
that and metamaterials open the door to this new design paradigm
for optics, providing the properties required to give complete control
of light. One potential application would be to steer light around a
hidden region, creating a cloak of invisibility.
