Abstract
In this study, the characteristics of surface plasma waves (SPWs) propagating in multilayer thin film are determined by the refractive indices of materials and the thickness of metal film sandwiched between these materials. A prism coupler is used to create the SPWs. The intensities of SPWs generated on different interfaces are discussed and the damping rates of SPWs on those interfaces are calculated. This study leads to a conclusion that the damping rate of SPW is much more sensitive to thinner metal film.
