Based on the graphene floating gate, a tunable terahertz metamaterial absorber is proposed. Compared with the traditional graphene-dielectric-metal absorber, our absorber has the property of being non-volatile and capacity for anti-interference. Using the finite element method, the paper investigates the absorption spectra, the electric field energy distribution, the tunability and the physical mechanism. In addition, we also analyse the influence of geometry, polarization and incident angles on the absorption. Simulation results show
