2109936 9222846 PCTABScor01 This invention presents a process for the production of a lens with a given variable refraction index by fixing together several parts, at least some of them have a variable refraction index. The realization of the desired refraction index of the parts can be achieved by compressing dielectric material of a first shape into its final shape or by a doping or a mixing process respectively. Outer parts, which extend to the outer surface of the lens to be produced, have a pyramid-like shape with a pointed or truncated apex respectively. In the first case the apexes of the outer parts meet in the symmetry point of said lens; in the latter case a center part is used which is located around said symmetry point. It is also possible that some of the outer parts used have pointed apexes and the rest of them has got truncated apexes. In this case a center part used is easy to fix near the symmetry point of the lens. If dielectric material is taken, the lens to be produced can preferably be used as part of microwave antenna system.
