Title:
METHOD FOR DESIGNING GRADIENT INDEX LENS AND ANTENNA DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/203748
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for designing a gradient index lens making it possible to easily and accurately drive an antenna. According to the present invention, a gradient index lens is designed by: setting a virtual domain in which a focal plane of a curved shape in a uniform refractive index-type lens having a uniform refractive index is included in a boundary, and a physical domain in which a focal plane of a planar shape in a gradient index lens having a non-uniform refractive index is included in a boundary and which is a quasiconformal mapping onto the virtual domain; using, as a virtual medium parameter, a medium parameter including permittivity and/or electromagnetic permeability for characterizing the virtual domain, and calculating, as a physical medium parameter in the physical domain, a quasiconformal mapping onto the virtual medium parameter; spatially arranging a preset medium parameter adjustment member; and designing the lens according to the physical medium parameter.
