现有的理论旨在解释二维亚波长孔阵列穿透金属薄膜的异常光透射现象。Ebbesen，H.J. Lezec，H.F. Ghaemi，T. Thio和P.A.沃尔夫，自然~伦敦！391、667 ~1998年！#它们都具有以下共同的功能：不是研究由孔阵列产生的二维交叉光栅，而是考虑具有无限狭缝的一维光栅。我们表明，这样的简化引入了一个有效的通道，在层状光栅，这是不存在的孔阵列的光传输。因此，为了解释Ebbesen等人观察到的相对较高的透射率，必须考虑阵列中孔的存在。在本文中，我们开发了一个二维分析的实验进行Ebbesen等人。没有简化介绍。这使我们能够在理论上获得Ebbesen等人报告的长波长峰值，其光栅厚度与这些作者使用的光栅厚度相同。我们还详细审查和研究了致力于这一非常令人惊讶的效果的各种贡献。
The existing theories which aim to explain the extraordinary optical transmission of a metallic film pierced by a two-dimensional subwavelength hole array @T.W. Ebbesen, H.J. Lezec, H.F. Ghaemi, T. Thio, and P.A. Wolff, Natural ~London! 391, 667 ~1998!# all have in common the following feature: instead of studying the two-dimensional crossed grating resulting from the hole array, they consider a one-dimensional grating with infinite slits. We show that such a simplification introduces an efficient channel for light transmission in lamellar gratings, which does not exist for hole arrays . Therefore in order to explain the relatively high transmission observed by Ebbesen et al., it is necessary to take into account the existence of the holes in the array. In this paper we develop a two-dimensional analysis of the experiment performed by Ebbesen et al. No simplification is introduced. This allows us to obtain theoretically the long-wavelength peak reported by Ebbesen et al. with the same grating thickness as the one used by these authors . We also review and study in detail the various contributions devoted to this very surprising effect.
