Development and application of terahertz metamaterials

超材料是人工构造的材料，在自然获得的材料中具有介电常数和磁导率。在这项研究中，我们设计、制造和表征了太赫兹区的超材料。在制备方面，使用超细喷墨打印机制作平面和多层超材料，并用太赫兹时域光谱进行评估。制作了负载金属原子的光导天线，证明了光脉冲可以控制发射光谱。

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.
