In this talk, I will introduce recent research findings on metasurface designs that exhibit exceptional optical properties beyond those found in natural materials. Specifically, I will show that gate-induced switching and linear modulation of terahertz waves can be achieved in a hybrid material system comprising artificially constructed meta-atoms and an atomically thin graphene layer. Additionally, I will highlight our recent research findings on THz near-field spectroscopy in various research fields. This outcome holds potential for the basis of studying charge distribution in space over a picosecond time scale, which has been challenging to observe in the past.
