Abstract:
1. An apparatus, the apparatus including a lens configured to allow electromagnetic radiation to pass through the lens, the lens having a first face and a second face, and being formed of a lens material, the first face and second face each being planar, the lens having an internal index profile configured to produce a predetermined convergence or divergence of electromagnetic radiation passing through the lens from said first face to said second face, the internal index profile anisotropically and/or inhomogeneously structured in three dimensions to represent a coordinate transformation in three dimensions, said coordinate transformation being a mathematical transformation from a pre-existing first geometry of curved spatial volume to a second geometry of planar spatial volume or vice versa, said second spatial volume bound by said first face and said second face, modification of the radiation beam being achieved through the internal index profile within the lens material.
