| Research Abstract |
For the realization of graphene metamaterials, graphene deposition technique on a silicone substrate and their layer/defect characterization method using micro-Raman spectroscopy have been established. We have fabricated and characterized graphene metamaterials, and distinctive infrared absorptions were observed at 6 THz (50 μm in wavelength). The corresponding numerical simulation based on finite-element-method revealed that the infrared absorptions resulted from localized plasmon resonances in the structured graphene.
