<<So? If you carefully control the location of
materials
within an overall composite - which it sounds like may
have happened here - you can create a lens (of one
material, with a certain refractive index) inside a
flat sheet (where the rest of the material is some
other material, probably with a refractive index much
closer to air), without bending any laws of physics.>>
Yes, resulting in the development of vastly, improved telescopes for spysats,
and especially astronomical telescopes, and whatever these might uncover.
Improved capabilities for holography, as well as optical computing. Other
possibilities might include greatly enhanced fresnel lenses for solar
heating, and or photovoltaics, and perhaps themionic conversion. According to
the article, Eleftheriades and his team weren't certain that what they had
discovered was possible, and this was last December. Seems like a useful
tool-set. We'll see house this discovery gets used and how quickly.
