Abstract
Luneberg lenses are commonly fabricated from a number of constant dielectric concentric shells to approximate the continuous dielectric distribution of the Luneberg lens formula. This paper discusses the relationship between the number of shells and the aperture efficiency as well as the adverse effects that air gaps between layers can have on the lens gain.
