In this paper， a dual-tunable triple-band absorber based on bulk Dirac semimetal （BDS） and vanadium dioxide （VO₂） is proposed. The electromagnetic properties of the absorber are analyzed by the finite difference time domain method and equivalent circuit model （ECM）. When the VO₂ is in fully metallic state， the absorption spectrum of the dual-tunable absorber exhibits three obvious absorption peaks with the average absorptance being 98.64%. The resonant frequencies and absorptivity of the absorber can be dynamically controlled by adjusting the Fermi energies of BDS and the conductivities of VO₂. Finally， the relationships between the absorptivity of the dual-tunable absorber and the different thicknesses of the BDS， VO₂ and immediate dielectric layers are further discussed. This work provides potential applications in the designs of multi-banddual-tunable filters and absorbers.
