I’ve been following the development of meta-materials for a
few years now, basically a meta-material is a compound material which has a
negative refractive index. You can read a LOT more about them here Meta-material wiki. In summary
that means, and I quote “Negative refractive index materials appear to permit
the creation of super-lenses which can have a spatial resolution below that of
the wavelength”. In summary-summary for those less blessed with a deep
understanding of optical or wave physics it means that waves are refracted at
an interface in the reverse sense to that normally expected. i.e. instead of
bending one way they bend the other way. If you could build lenses out of a
meta-material, convex lenses would scatter and concave lenses would focus.
