▎ 摘　　要

NOVELTY - The absorber has a unit cell provided with carbon black, carbon nanotube, carbon fiber and graphene. The dielectric loss of absorber is controlled by changing the strut diameter. The unit cell is provided with a multi-layer composite structure that is manufactured by combining the unit cell with different diameters. The composite structure is made of Kelvin structure, octet-truss structure, body-centered cubic lattice structure, simple cubic triple minilal surface (SC-TPMS) structure, cubic cellular core (CCC) structure and honeycomb structure. USE - Used as mechanical meta-structure based electromagnetic wave absorber. ADVANTAGE - The absorber has light weight, high rigidity and broadband electromagnetic wave absorption characteristics. The absorber can be manufactured through three-dimensional (3D) printing so as to easily implement complex overall shape. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of electromagnetic wave absorption and light-weight high rigidity structure.
