摘要
Using the time-dependent LDA method, we investigate the tunability of the optical polarizability of small metallic nanoshells. We show that the energies of the two dipolar plasmon resonances vary with the ratio of shell thickness to particle radius in a manner similar to what has been predicted using classical Mie scattering and semiclassical models for uniform metallic shell structures.
