Some thin metallic films show anomalous optical properties, namely, that both energetic position and magnitude of the absorption bands depend on the film thickness. An interpretation, usually accepted, is based on a direct excitation of surface plasmons by means of the granular structure or the roughnesses of the films. The existence of these anomalous bands are explained, independently of the surface irregularities, if we assume a localized absorption.
一些薄金属膜呈现出异常的光学特性，即吸收带的能量位置和幅度都取决于膜的厚度。一种通常被接受的解释是基于通过薄膜的颗粒结构或粗糙度对表面等离子体激元的直接激发。如果我们假设存在局部吸收，那么这些异常带的存在可以独立于表面不规则性得到解释。
