Tunable Hybrid Terahertz Metamaterials Based on VO2 Phase Transition

In this paper, a series of proof-of-concept designs for highly tunable hybrid THz metamaterials based on the phase transition of vanadium dioxide (VO ₂ ) are presented. In particular, we verify by full-wave simulations the tunable properties of the hybrid metamaterials including Fano resonances, perfect absorption bands and THz magnetism. Our results indicate that an integration of VO ₂ structures and conventional metallic resonating components can be used to create THz metamaterials with properties that can be dynamically tuned over a large scale.
