Simulation and experimental studies are carried out on single‐layer and double‐layer embedded metal meshes (SLEMM and DLEMM) to assess their performance as transparent electromagnetic interference (EMI) shielding. The structures consist of silver meshes embedded in polyethylene terephthalate (PET). As a transparent electrode, SLEMMs exhibit a transparency of 82.7% and a sheet resistance of 0.61 Ωsq−1 as well as 91.0% and 1.49 Ωsq−1. This performance corresponds to figures of merit of 3101 and 2620, respectively. The SLEMMs achieve 48.0 dB EMI shielding efficiency (SE) in the frequency range of 8–18 GHz (X‐ and Ku‐bands) with 91% visible transmission and 56.2 dB EMI SE with 82.7% visible transmission. Samples exhibit stable performance after 1000 bending cycles with a radius of curvature of 4 mm and 60 tape test cycles. DLEMMs consist of fabricating SLEMM on opposite sides of the substrate where the distance can be varied using a spacer. Simulations are performed to investigate how varying spacer distance between two layers of metal meshes influences the EMI SE. DLEMMs are fabricated and achieved an EMI SE of 77.7 dB with 81.7% visible transmission. SLEMMs and DLEMMs may have a wide variety of applications in aerospace, medical, and military applications.

单层和双层嵌入式金属网可实现灵活、高透明的电磁干扰屏蔽

对单层和双层嵌入式金属网（SLEMM 和 DLEMM）进行了仿真和实验研究，以评估其作为透明电磁干扰（EMI）屏蔽的性能。该结构由嵌入聚对苯二甲酸乙二醇酯 (PET) 中的银网组成。作为透明电极，SLEMM 的透明度为 82.7%，方块电阻为 0.61 Ωsq−1以及 91.0% 和 1.49 Ωsq−1。该性能分别对应于 3101 和 2620 的品质因数。 SLEMM 在 8-18 GHz（X 和 Ku 频段）频率范围内实现了 48.0 dB EMI 屏蔽效率 (SE)，可见光透射率为 91%，可见光透射率为 56.2 dB EMI SE，可见光透射率为 82.7%。样品经过1000次曲率半径为4毫米的弯曲循环和60次胶带测试循环后表现出稳定的性能。 DLEMM 由在基板的相对两侧制造 SLEMM 组成，其中可以使用垫片改变距离。通过仿真来研究两层金属网之间不同的间隔距离如何影响 EMI SE。 DLEMM 已制造并实现了 77.7 dB 的 EMI SE 和 81.7% 的可见光透射率。 SLEMM 和 DLEMM 在航空航天、医疗和军事应用中具有广泛的应用。
