我们从理论上研究了金属薄膜中具有立体纳米孔阵列的特殊等离子体结构，该结构具有在光频率下操纵光学偏振的卓越能力。主要特性是通过适当的结构设计并结合提高的传输效率，可以在传输中获得包括完整90度旋光的任何线偏振态。随着偏振的变化，传输侧表面上的表面等离子体传播也可以被调制。此外，通过引入依赖于频率的耦合系数来描述立体等离子体系统中的旋光特性，从而开发了分析耦合模式方法（CMM）。 (C)2011 美国光学学会
We theoretically study a particular plasmonic structure with stereo nanoholes array in metallic film, which has remarkable abilities to manipulate the optical polarizations at optical frequencies. The main property is that any linear polarization states including a complete 90 degrees optical rotation can be obtained in transmission by proper structural design in combination of enhanced transmission efficiency. Together with the polarization change, surface plasmon propagation bounded on the surface of transmission side also can be modulated. Furthermore, an analytical Coupled Mode Method (CMM) is developed by introducing a frequency dependent coupling coefficient to describe such optical rotation property in stereo plasmonic systems.
