A field picture of wave propagation in inhomogeneous dielectric lenses

Research output: Contribution to journalArticle

Abstract

This article presents the radiation and scattering patterns, and the interior field distributions, of three inhomogeneous dielectric lenses: the Luneburg, Maxwell fish-eye, and Eaton-Lippmann lenses. The purpose is to provide a picture of wave propagation through these lenses. A better understanding of the field picture, especially the nature of the focal points, is helpful to the practical design of the lenses.
