Outline of Final Research Achievements

We fabricated various two- and three-dimensional electromagnetic metamaterials based on the dielectrics and semiconductors using novel techniques such as the ultra-fine inkjet processing, chemical etching, and laser machining, and so on. We evaluated their optical properties and clarify the exotic characteristics of THz metamaterials induced by the structural resonances. We also demonstrated the electromagnetic induced transparency, THz switching element, THz element, and surface wave along the interface of the metamaterial with the chirality.
