原始语种摘要: Angular dependences of ellipsometric parameters $\psi$ and $\Delta$ at external reflection as well as an internal reflection coefficient are experimentally measured for hybrid structures based on thin Au, Ag or Cu films protected by dielectric layers HfO$_2$ or MgF$_2$. Using numerical matrix method, appropriate angular dependences for such multilayer systems are calculated. Despite of the differences obtained at modelling of optical parameters of the objects between the ordinary (external reflection) and plasmonic (internal reflection) modes, the theoretical results are in good agreement with the experimental data. Angular positions of plasmonic attenuated internal reflection minima in Kretschmann geometry for the samples are calculated as functions of a refractive index $n$ of a...
