| Research Abstract |
Metamaterials are artificially structured materials, which have permittivity and permeability in naturally obtained materials. In this study, metamaterials in the terahertz region are designed, fabricated, and characterized. For fabrication, planar and multi-layered metamaterials are made using a super-fine ink-jet printer and evaluated by the terahertz time-domain spectroscopy. Photoconductive antennas loaded with meta-atoms are fabricated and it is demonstrated that the control of the emission spectra is possible by optical pulses.
