In theory, attenuating electromagnetic waves mainly rely on a strong three-dimensional (3D) network constructed by conducting materials [1]. In addition, enhancing the multi-interface texture of 3D conductive network also facilitates the attenuation of electromagnetic waves by shielding materials, which has the advantage of absorbing more electromagnetic waves by interfacial polarization, and appeared to be better than the metal plate structure dominated by the shielding reflection [2].
