研究了两表面都有浅波纹的金属薄膜的光学响应，发现当横向磁辐射在平行于光栅凹槽的平面上入射时，该结构支持一个强耦合的表面等离子激元极化子。模型证实了这种强激发模式是短程表面等离子激元极化子，并且在光谱可见部分实验中证实了它的存在。
The optical response of a thin metallic film with shallow corrugations on both surfaces is explored and the structure is found to support a strongly coupled surface plasmon polariton when transverse magnetic radiation is incident in a plane parallel to the grating grooves. Modeling confirms that this strongly excited mode is the short range surface plasmon polariton and its presence is confirmed experimentally in the visible part of the spectrum.
