我们提出了一种多腔谐振结构，该结构通过采用两个相对的超薄银基薄膜形成法布里-帕姆罗特（F-P）腔，并在两者之间插入一个或两个金属网状层来建立。与单F-P腔相比，具有一个金属网状层的多腔结构的平均屏蔽效率提高了约37%，并且在550 nm处保持了80%以上的透过率。通过插入两个金属网格层，可以实现屏蔽效率（SE）的更显着提高~ 108%。所提出的多腔结构提供了一种消除透明电磁干扰屏蔽障碍的策略。
We propose a multi-cavity resonant architecture that is established by employing two opposing ultrathin silver-based films to form a Fabry-Pérot (F-P) cavity and inserting one or two metallic mesh layers in between. Compared with the single F-P cavity, the multi-cavity architecture with one metallic mesh layer experimentally exhibits a ∼37% improvement in the average shielding effectiveness and maintains a transmittance over 80% at 550 nm. A more significant improvement of ∼108% in shielding effectiveness (SE) can be achieved by inserting two metallic mesh layers. The proposed multi-cavity architecture provides a strategy for removal of the hindrance to transparent electromagnetic interference shielding.
