摘要：

Multipolar effects in the polarizability of metallic potassium particles on a silicon substrate were studied using differential reflectance spectroscopy. The experimental spectra were compared with calculations of the effective polarizability of particles of different shapes leading to the conclusion that the resonances in the spectra correspond to excitations of substrate-induced multipolar modes in the particle-substrate system.
