▎ 摘　　要

NOVELTY - The absorber has a wave absorbing unit provided with a conductive reflecting layer, a medium layer and a micro-structure unit layer. The micro-structure unit layer is provided with a hollow snowflake-shaped structure. A branch end of a big branch is connected with a side of a regular hexagon center. Two sides of the big branch are symmetrically provided with three groups of small branches. Distance between two adjacent groups of the small branches is equal. A material of the micro-structure unit layer is selected from one of metal, graphene or indium tin oxide. USE - Multi-band terahertz wave absorber based on super-structure for terahertz detection and stealth technology. ADVANTAGE - The absorber has absorption peaks in 0.2-3 terahertz wave band and high absorption rate. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a multi-band terahertz wave absorber.
