Theoretical investigation of a multifunctional tunable terahertz metamaterial absorber based on vanadium dioxide and graphene
This paper introduces and investigates a graphene and vanadium dioxide based metamaterial absorber in the terahertz region. The proposed structure consists of four layers (gold, dielectric layer, graphene, and VO₂) and is designed using the phase transition properties of VO₂ and the tunability of graphene. Simulation results show that in the insulating phase, the structure operates as a narrowband absorber with distinct absorption peaks, while in the metallic phase, broadband performance with over 80% absorption in the 4.28–7.55 THz range is observed. The structure’s performance was analyzed through the electric field distribution and surface current, and the effects of temperature variations and chemical potential adjustments on the absorption spectrum were studied. A distinguishing feature of this structure is its tunable absorption enabled by temperature and chemical potential changes. The key attributes of this structure, including tunability, sensitivity to temperature changes, and its application in logic gates, make it a suitable candidate for sensing and optical information processing applications in the terahertz region.
