    Abstract:

    Terahertz(THz) Surface Plasmons Polaritons(SPPs) can mimic optical Surface Plasmons(SPs) and obtain similar optical properties with periodic sub-wavelength structures, which typically consist of propagating SPPs and Localized Surface Plasmons(LSPs). In this work, graphene is utilized as the active stimuli to dynamically control the amplitude, frequency, and phase of SPPs and reconfigure the resonant modes of LSPs at various bias voltages. Such design provides new solutions for active control of SPPs and LSPs at THz frequencies.
