本文综述了近年来金属薄膜中亚波长孔径光传输的研究进展。主要关注的是十多年前发现的周期性孔阵列中的异常光传输现象。结果表明，表面电磁模式在谐振传输的出现中起着关键作用。这些模式也被证明是在增强传输和光束的光发现在周期性波纹包围的单个光圈的根源。本文综述了这一课题的理论和实验研究。为了清楚起见，在一个共同的理论框架内分析了在所考虑的不同结构中操作的物理机制。几个应用的基础上的传输特性的亚波长孔径也得到解决。
This review provides a perspective on the recent developments in the transmission of light through subwavelength apertures in metal films. The main focus is on the phenomenon of extraordinary optical transmission in periodic hole arrays, discovered over a decade ago. It is shown that surface electromagnetic modes play a key role in the emergence of the resonant transmission. These modes are also shown to be at the root of both the enhanced transmission and beaming of light found in single apertures surrounded by periodic corrugations. This review describes both the theoretical and experimental aspects of the subject. For clarity, the physical mechanisms operating in the different structures considered are analyzed within a common theoretical framework. Several applications based on the transmission properties of subwavelength apertures are also addressed.
