Outline of Final Research Achievements

Novel optical devises have been developed by using metamaterials whose optical properties are designed by artificial sub-wavelength structures. The metamaterials are applied to not only passive devises but also light sources. The possibility to control propagation of terahertz waves and radiation spectra by the metamaterial elements is demonstrated. The polarization of the terahertz radiation can be designed by time-domain propagation of the terahertz pulses on the electrodes. The radiation spectra can be tuned by controlling the coupling between the terahertz source and sub-wavelength resonators.
