Outline of Final Research Achievements

The aim of this study is to develop high-performance metamaterials using 2D oxide nanosheets. Through electromagnetic field analysis, we developed optimal meatamaterial structures based on 2D oxide nanosheets. We utilized 2D oxide nanosheets as building blocks in solution-based assembly, and successfully fabricated superlattice films with artificial modulation of permittivity and permeability. In particular, (RuO2/Ca2Nb3O10/RuO2) exhibited negative refractive index in the near IR wavelength.
