Excitation of surface plasmon-polaritons by attenuated total reflection in graphene-based metasurface

In this work we theoretically analyze the electromagnetic behavior of graphene-based metasurface, consisting on arranged array of graphene stripes, under attenuated total reflection conditions. We investigate surface plasmon-polaritons excitation at terahertz and sub-terahertz frequencies. We show that surface plasmon-polaritons may be excited in the metasurface for some orientation with respect to incident wave plane. Effectivity of surface plasmon-polaritons excitation depends on graphene chemical potential and graphene stripes width. We believe that our results open a new road for graphene metasurface based terahertz devices, such as modulators.
