Abstract. Dual layer planar Luneburg
lens is considered. The lens provides 3600 scanning sector without
effect of shading. One of the possible variant of the lens is analyzes in terms
of coupled waves theory. Influence of phase errors caused by presence of two
layers is analyzed. Dual layer Luneburg lens in the form of two parallel plate
waveguides with non – uniform dielectric filling and impedance films as
screens is considered. Two dimensional metal strip arrays are used as impedance
films. Parameters of the device are discussed.
Keywords: Luneburg lens, coupled
waves theory, parallel plate waveguide, impedance film.
