Outline of Final Research Achievements

Transmission elements based on aperture-coupled-patch FSSs have been proposed for obtaining novel artificial materials with right-handed nature. Both the element shape and the multi-layer structure are optimized to improve the frequency response. The proposed artificial elements are applied to design of flat lenses. Reflection elements with multiple convex resonant-strips have been also proposed for dual-polarization use. The shape optimization to control multiple resonance behaviors has been performed for achieving low cross-polarization characteristics. The proposed artificial elements are applied to design of aperture antennas with both linear and circular polarization. Primary radiators with artificial impedance surfaces have been developed and applied to a backfire primary radiator for rotational symmetric reflector. The performance of the developed artificial materials and antennas are confirmed numerically and experimentally.
