摘要：

Surface plasmon energies of single and oxidized spheres half-embedded on a planar support are calculated in the framework of the classical dielectric theory. Simple analytic expressions are obtained. New resonances appear related to the coupling between both media. The main difference between a supported sphere and an isolated sphere is the splitting of the multipolar energy modes, according to their parity. The support effect on EELS spectra is analyzed for some cases of experimental interest in electron microscopy.
