▎ 摘　　要

The effect of different superimposed structures on the transparent electromagnetic interference (EMI) shielding performance of graphene is reported. The average optical transmittance of a graphene/quartz sample with different superimposed structures in the Vis-near-infrared spectrum (400-2400nm) is almost the same (84%). The EMI shielding efficiency (EMI SE) of the two samples after superposition is 4.85-3.96dB, which has been greatly improved compared to the single sample. The EMI SE of the backward superposition is 0.5-0.2dB larger than the interval superposition. The EMI SE of the interval superposition is 0.8-0.2dB larger than the forward superposition. The backward superposition of graphene can absorb 55% of the electromagnetic waves, reflect 10%, and only 35% of the electromagnetic waves pass. We envision that graphene can obtain high EMI SE through different superimposed structures in the theoretical research and applications.
