▎ 摘　　要

NOVELTY - The selector has a gold layer (1) and a silicon dioxide layer (2) orderly laminated with each other. A surface of the silicon dioxide layer is provided with a graphene resonant structure (3). The graphene resonant structure is provided with a multi-layer laminated square ring (4). A middle portion of an edge of the square ring is provided with a square block (5). The middle portion of an inner edge of the square ring is provided with a wave-shaped topological boundary. Four corners of the square ring are respectively provided with four transmission hole lattices. An array grid is formed between the transmission hole lattices. USE - Adjustable graphene terahertz frequency selector. ADVANTAGE - The selector achieves high absorption performance to a terahertz wave, and realizes control of absorption peak and absorption frequency. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an adjustable graphene terahertz frequency selector.
