Abstract: In order to solve the electromagnetic radiation brought by 5G mm-wave, and environmental secondary pollution, high radar scattering cross section, optical opaque and difficult to conformal caused by the existing electromagnetic shielding materials. A multi-performances electromagnetic shielding material based on a metamaterial absorber was proposed in this paper, which can meet the green shielding index g_s≥1 with low radar cross section (RCS), optical transparency, and flexible performances. This electromagnetic shielding material belongs to a manually designable multi-layer structure, in which the transparent conductive material indium tin oxide was used as the periodic resonant unit structure and the underlying floor material. The transparent materials polyethylene terephthalate and polyvinyl chloride were used as the dielectric layer. The consistency between simulation and experimental results shows that in the frequency range of 22-30 GHz, and un-conformal and conformal angle of 45° states, the proposed shielding material can achieve >30 dB green effective electromagnetic shielding and >5 dB RCS reduction. The equivalent circuit of theoretical derivation, and equivalent parameters, field distribution demonstrated the principle of absorption shielding. The green multi-performances electromagnetic shielding material accurately covers the 5G mm-wave n257, n258, and n261 frequency bands, which can effectively solve the electromagnetic interference problem caused by these frequency bands.
