Abstract

We report a nested multi-ring array metallic mesh (NMA-MM) that shows a highly uniform diffraction pattern theoretically and experimentally. Then a high-performance transparent electromagnetic interference (EMI) shielding structure is constituted by the double-layer interlaced NMA-MMs separated by transparent quartz-glass substrate. Experimental results show that double-layer interlaced NMA-MM structure exhibits a shielding effectiveness (SE) of over 27 dB in the Ku-band, with a maximal SE of 37 dB at 12 GHz, normalized optical transmittance of 90%, and minimal image quality degradation due to the interlaced arrangement. It thus shows great potential for practical applications in transparent EMI shielding devices.

摘要

我们报道了一种嵌套式多环阵列金属网（NMA-MM），其在理论和实验上均呈现出高度均匀的衍射图案。然后，由被透明石英玻璃基板隔开的双层交错NMA-MM构成了一种高性能透明电磁干扰（EMI）屏蔽结构。实验结果表明，双层交错NMA-MM结构在Ku波段的屏蔽效能（SE）超过27 dB，在12 GHz时最大SE为37 dB，归一化光学透过率为90%，并且由于交错排列导致的图像质量退化最小。因此，它在透明EMI屏蔽装置的实际应用中显示出巨大潜力。
