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.
