Terahertz technology provides wide range applications and graphene has appeared as a highly promising material to control terahertz wave. Here we propose a terahertz amplitude modulator which consists of a single-layer graphene and subwavelength metal structure surface (SMSS). Graphene is core regulatory elements which controls the terahertz wave by means of tuning Fermi level in graphene. SMSS acts as the gate electrode and meanwhile plays a role of frequency selection that the appropriate modulation frequency bandwidth can be chosen.
