Abstract: Conventional metamaterials suffer from the high inherent Ohmic loss in the metal components, especially in the visible and infrared regions. In this thesis, the possibilities of using low-loss dielectric metasurfaces and spoof plasmon surfaces to avoid the absorption loss have been investigated through both numerical and experimental studies. The controls of multiple light properties by these low-loss metamaterials are demonstrated. More specifically, an all-dielectric metasurface with high reflection and full range phase tuning capability is demonstrated in the THz; a half-wave plate in reflection mode is achieved with dielectric resonator; a dielectric chiral planar metasurface is designed to significantly surpass the optical chirality limit in plasmonic planar metasurfaces; a waveguide supporting spoof surface plasmon is utilized to achieve a micro-fluidic sensing device.
