摘要
采用衰减全反射（ＡＴＲ）技术，单波长激励金属膜表面等离子激元波（ＳＰＷ）的共振吸收峰，在考虑金属膜表面粗糙度的情况下，用非线性最小二乘曲线拟合同时确定出了金属膜厚度与介电常数，并在另一波长下获得验证。
In this paper, the surface plasma wave(SPW)on the interface of medal-electricmedium was excited with one wavelength by using the angle scanning ATR method and thethickness and dielectric constants of metal films were measured by a nonlinear least-squarecure-fitting method.
