Abstract. Numerical electromagnetic modeling of two types of
metal-dielectric planar Luneburg lenses: a radially stratified and based on ring
dielectric EBG structure have been made. Simulation is carried out using three methods: a parabolic
equation, integral equations and finite element method. The problems of
radiation and diffraction of a plane wave considered. The broadband properties of planar
Luneburg lenses have been investigated.
Keywords: Planar lens, Luneburg lens, broadband antennas, integral
equation, parabolic equation, finite element method.
