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.
