We design a broadband absorber formed by placing the cross-shaped metallic resonators, whose vertical and horizontal arms have difference length, with 90° rotated within a super-unit-cell arranged in mirror symmetry. Simulation results indicate that absorption efficiency greater than 95% can be achieved in a broadband frequency region under normal incidence. We employ a design scheme with the integration of graphene and VO₂ thin film, which allows independent electric tuning and thermal tuning. Our results reveal that the resonance will be blue-shifted with the increase of Fermi level and red-shifted with the increase of temperature. it thus broadens the tuning range of metamaterial absorbers by combining the electric tuning of graphene with the thermal tuning of VO₂ thin film. this structure may have great application potential in frequency selective detectors and testing technology
