SPHERICAL LENS WITH VARYING REFRACTIVE INDEX Russian patent published in 1996 - IPC

FIELD: aerial equipment. SUBSTANCE: invention refers to lens aerials. Spherical lens with varying refractive index is made of cubic modules 1 on which side faces there are manufactured mating grooves 3 and protrusions 2 by means of which these modules 1 are connected into parallel horizontal layers. Adjacent modules 1 of each layer are displaced by vertical line relative to each other. Modules are produced from homogeneous dielectric material with different values of dielectric permittivity and are placed in layers in agreement with specified rule of change of dielectric permittivity. Lens is fitted with belt 6 with units 7 for attachment of lens. EFFECT: improved operational capabilities, simplified design. 3 dwg
