Outline of Final Research Achievements

We developed a technique to confine terahertz electromagnetic waves to a space smaller than the wavelength. The structure that makes this possible and a terahertz sensor enabled more detailed analysis. We applied it to the study of behavior of electrons in materials and successfully obtained more microscopic information.

Academic Significance and Societal Importance of the Research Achievements

テラヘルツ領域の研究から、物質や生命の背後にある謎を解き明かすための糸口をつかむことができると期待されている。そのためには、波長による制限を超えてより極微の世界を観察するための技術が必要となっている。本研究成果はこの方向を進めることに貢献することが期待できる。
