讨论了周期性织构金属薄膜作为从薄膜发射器件中提取光的方法。所提出的方案包括将发射器耦合到结构的表面等离子体激元模式，并通过将该模式散射到周期性微结构来产生有用的辐射。提出了涉及的概念，并探索了与几个特定候选结构相关联的细节。评估了这些结构增强发射过程的潜力，并讨论了可能存在的问题，特别是金属损耗。
Periodically textured metallic films are discussed as a method of extracting light from thin-film emissive devices. The proposed scheme involves coupling the emitters to a surface plasmon polariton mode of the structure and producing useful radiation by scattering this mode off periodic microstructure. The concepts involved are developed and the details associated with several specific candidate structures explored. The potential of these structures to enhance the emissive process is assessed, and possible problems, especially loss in the metal, are discussed.
