Abstract

Finding the optimal optoelectronic properties (zero-order optical transmittance, shielding effectiveness, and stray light uniformity) of metallic mesh is significant for its application in electromagnetic interference shielding areas. However, there are few relevant studies at present. Based on optoelectronic properties, we propose a comprehensive evaluation factor Q, which is simple in form and can be used to evaluate the mesh with different parameters in a simple and efficient way. The effectivity of Q is verified by comparing the trend of Q values with the evaluation results of the technique for order preference by similarity to ideal solution (TOPSIS). The evaluation factor Q can also be extended to evaluate the optoelectronic properties of different kinds of metallic meshes, which makes it extremely favorable for metallic mesh design and application.

摘要

获取金属网栅最佳光电性能 (零级光学透光率、 电磁屏蔽效能和杂散光均匀性) 对其在透明电磁屏蔽领域的应用具有重要价值. 然而, 目前相关研究较少. 本文提出一种基于金属网栅光电性能的形式简单的综合评价因子Q, 可简便有效地用于不同结构参数的金属网栅光电性能评估. 评价因子Q值与TOPSIS的评估结果变化趋势一致, 验证了评价因子Q的有效性. 评价因子Q还可以对不同图案的金属网栅光电性能进行评估, 使其在金属网栅的设计和应用中具有十分广泛的应用前景.
