Abstract

Optical properties of a silver-island film are interpreted by taking account of retarded dipole–dipole interactions between island particles instead of the static-field interaction. The discrepancies between the values of the structural parameters evaluated from electron micrographs and those evaluated optically with the assumption of the static-field dipole–dipole interaction can be thus interpreted. The retarded dipole–dipole interactions as well as the size effect also broaden the width of the plasma-resonance absorption peaks.
