Here we report the first (as far as we know) experimental observation of extremely high enhancement factor due to elastic surface plasmon-polariton scattering by surface singularities.We have observed strong diffraction of surface plasmon-polaritons by shallow diffraction grating while its illumination by evanescent or volume waves do not shows any traces of diffraction structure in space distribution of scattered light.
在此，我们报告了（据我们所知）首次通过表面奇点引起的弹性表面等离激元 - 极化激元散射实现极高增强因子的实验观测结果。我们观察到表面等离激元 - 极化激元被浅衍射光栅强烈衍射，而当用倏逝波或体波照射时，散射光的空间分布中未显示出任何衍射结构的痕迹。
