▎ 摘　　要

NOVELTY - Dynamically adjustable graphene metamaterial terahertz device based on anapole mode comprises a ring structure single-layer metamaterial, which is composed of two symmetrically arranged metal semi-circular split rings. Each split ring is composed of a ring body and an extension arm, and the extension arm extends from the ring body toward the center of the ring body. An opening is provided between the two split rings, and the opening penetrates the diameter of the ring structure formed by the two semi-circular split rings, and the extending arm opens vertically. The openings at the ring body and the extension arm are filled with graphene. USE - Used as dynamically adjustable graphene metamaterial terahertz device based on anapole mode. ADVANTAGE - The device adjusts the Fermi energy of graphene through electrostatic doping, tuns the conductivity of graphene and realizes dynamic tuning of the terahertz anapole response. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for preparing dynamically adjustable graphene metamaterial terahertz device based on anapole mode. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic representation of the dynamically adjustable graphene metamaterial terahertz device based on anapole mode.
