▎ 摘　　要

NOVELTY - The device has a substrate formed with an insulation medium layer. An open resonance ring graphene structure (3) is provided with the substrate. The open resonance ring graphene structure is formed with a parallel insulation medium layer. A first opening edge (7) is connected with a second opening edge (8). A third opening edge (9) is connected with a fourth opening edge (10). A first heave (11) is connected with a second heave (12). A column (5) is connected with a vertical edge (4). A third heave (14) is connected with an outer side of the fourth opening edge. USE - Graphene based terahertz adjustable harmonic device for terahertz communication area. ADVANTAGE - The device avoids terahertz meta material tuner tuning problem. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene based terahertz adjustable harmonic device. Open resonance ring graphene structure (3) Vertical edge (4) Column (5) Opening edges (7-10) Heaves (11, 12, 14)
