| Outline of Final Research Achievements |
In this study, we aim to fabricate the structure that has multi-frequency resonances with the artificial materials called metamaterials. We designed and fabricated the coupled resonator structures where some resonators had interactions with each other through electromagnetic coupling. In these structures, the multi frequency resonant behavior was observed both in simulation and experiment. In addition, we fabricated metamaterial absorbers operated in terahertz region by utilizing those coupled resonator structures.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，結合共振器メタマテリアル構造によって複数の周波数で共鳴モードが生じることを確認し，それを用いてメタマテリアル吸収体を作製しました。このようなメタマテリアル吸収体は，電磁波の波長よりも十分に薄いのでその薄さを活かして，例えば，テラヘルツ波の吸収強度分布を温度分布としてサーモカメラなどで観測するような用途に応用可能ではないかと考えられます。
