摘要:

本文用解析和数值方法研究了周期性调制金属薄膜中的光衍射。没有调制,这些膜几乎是透明的。周期性的结果在异常的效果,如抑制的透射率伴随着强烈的增强的吸收率和镜面反射率,由于激发的表面等离子体激元。这些现象与众所周知的周期性调制光学厚金属膜的增强透明度相反。我们的理论分析可以作为这些有趣现象的实验研究的起点。

英文摘要:

We study light diffraction in the periodically modulated ultrathin metal films both analytically and numerically. Without modulation these films are almost transparent. The periodicity results in the anomalous effects, such as suppression of the transmittance accompanied by a strong enhancement of the absorptivity and specular reflectivity, due to excitation of the surface plasmon polaritons. These phenomena are opposite to the widely known enhanced transparency of periodically modulated optically thick metal films. Our theoretical analysis can be a starting point for the experimental investigation of these intriguing phenomena.
