Abstract:

Radially symmetric lenses are of great interest for use in antennas required to scan over wide angles. Common examples are the various approximations to the Luneburg lens. In this report, the simpler configuration of a lens constructed from a homogeneous core surrounded by a homogeneous shell is considered, with the homogeneous lens regarded as a special case. It is shown that almost all practical requirements can be satisfied by this type of lens and it is an attractive solution for millimetric wavelengths. Author
