Abstract (en)
[origin: WO2007003653A1] The invention concerns an inhomogeneous lens with Maxwell's Fish-eye type gradient index (1), made in the shape of a hemisphere. The invention is characterized in that the lens comprises N hemispheric concentric shells (2 to 4), with different discrete dielectric constants and mutually interlaced without void between the two successive shells, with 3 = N = 20, the discrete dielectric constants of the N shells being such that they define a discrete distribution close to the theoretical distribution of the index inside the lens.
