▎ 摘　　要

NOVELTY - The frequency selection surface has an intermediate layer (2) that is composed of a fractal square ring metal structure. Each unit of the bottom resonance layer (3) is composed of a metal square ring and a Jerusalem cross structure in the ring, so as to generate a wave transmission effect. A first dielectric substrate (4) is provided with a metallized vias (7). A top resonance layer (1) and the intermediate layer are fixedly connected through four support rods (8), and the three together produce a broadband absorbing effect. USE - Graphene-based absorption-integrated frequency selection surface for absorbing and transmitting waves used for radomes and electromagnetic shielding. ADVANTAGE - The frequency selection surface is provided with high plane integration, good out-of-band selectivity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the structure of frequency selection surface.
