论文摘要
虽然具有光传输和电磁屏蔽的功能材料是非常可取的,但只有很少的功能材料符合光电系统的严格电磁干扰(EMI)屏蔽标准。在这里,提出并通过实验证明了短短的微波导(SMW)阵列的设计策略,以使光变速箱和EMI屏蔽层解除。 SMW阵列包括截止金属微波导和短路二锡氧化物(ITO)连续导电膜,表现出90.4%的光学透射率高,超高频率频谱(0.2-1.3 GHz&1.7-18 GHZ)的平均值为62.2 dB。 Compared to previously reported works, an improvement of 19 dB in average shielding effectiveness has been achieved under the same level of light transmission, and the shielding frequency spectrum has been significantly expanded.已经对工作原理进行了深入解释,并研究了影响性能的因素以进行设计优化。
While functional materials with both light transmitting and electromagnetic shielding are highly desirable, only very few of them meet the stringent electromagnetic interference (EMI) shielding criteria for optoelectronic systems. Here, a design strategy of shorted micro-waveguides (SMWs) array to decouple the light transmission and EMI shielding is proposed and experimentally demonstrated. The array of SMWs, consisting of cut-off metallic micro-waveguides and shorting indium tin oxide (ITO) continuous conductive film, exhibits high optical transmittance of 90.4% and superior EMI shielding effectiveness of 62.2 dB on average over ultra-wide frequency spectrum (0.2-1.3 GHz & 1.7-18 GHz). Compared to previously reported works, an improvement of 19 dB in average shielding effectiveness has been achieved under the same level of light transmission, and the shielding frequency spectrum has been significantly expanded. The working principle has been explained in depth and factors influencing the performance have been investigated for design optimization.
