Outline of Final Research Achievements

(1) We developed the fabrication technology for ultra-small MIM (metal/insulator/metal) resonator arrays and demonstrated the enhancement of magnetic-dipole transition and second harmonic generation. (2) We achieved the dynamic beam steering by controlling the dispersion of meta-surfaces. (3) We achieved the perfect light absorption by impedance control. (4) We developed a mass production technology of meta-surfaces by nano imprinting, applied it to the fabrication of wavelength-selective thermal IR emitters, and achieved the reduction of energy consumption for a carbon dioxide gas sensor. (5) We developed meta-surfaces for enhancing luminescence and metamaterial polarizers thinner than the wavelength of light. (6) We clarified the condition to generate optical Dirac cones and extended this analysis to electronic Dirac cones. We published these achievements as 40 journal papers and 36 invited talks.
