Broadband Three-Mode Tunable Metamaterials Based on Graphene and Vanadium Oxide.

After 2 THz, the real part shows a rising trend and tends to 1, and the imaginary part shows a decreasing trend and tends to 0, and the effective impedance of the metamaterial matches with the free-space impedance, which achieves an effective absorption in the terahertz band.
