Geodesic Luneburg lenses for high power applications
Abstract
Lens antennas make use of a lens to modify the field distribution at the aperture of theantenna, which is typically fed by a single source. The lens is employed to transform thewaves arriving from the source into a desired radiation pattern. One lens that is interestingfor antenna designs is the Luneburg lens. A Luneburg lens is a graded-index lens thatperfectly transforms a spherical/cylindrical wave into a plane wave at the opposite side ofthe excitation. Luneburg lenses are an attractive solution for communications and radarsystems, and they are typically implemented with dielectric materials.For high-power applications, fully-metallic configurations are preferred. In this sense,the concept of geodesic lenses makes it possible to implement Luneburg lenses in whichthe waves propagate only in the air. The research on geodesic lenses has been recentlyrevitalized, specifically for designing new antennas for the new generation of satellitecommunications. With this project, we aim to explore the possibilities of geodesic lensesfor radar systems that handle a large amount of power.
