摘要：

We calculate the linear optical response of island films, considering, in particular, a statistical character of the geometry of the cluster assembly as well as electromagnetic interaction between the clusters in the film. The work involves Monte Carlo simulations of the island-film growth followed by aggregate calculations of the island-film optical extinction. The results of Monte Carlo simulations are compared with the transmission electron micrographs of silver island firms on fused silica. The optical response of the film has been approximated by the extinction of a statistical assembly of spheres, whose sizes and positions have been obtained from the Monte Carlo simulations. The comparison of the calculation with oblique incidence optical transmission spectra allows us to illuminate the role of the various effects contributing to the transmission behaviour of the films.
