Abstract In this work, we investigate electromagnetic responses in multilayered Ag/SiO2 nanoplates at optical frequencies. Electric and magnetic resonances, which originate from localized surface plasmons, are demonstrated by the effective permeability and permittivity, electric and magnetic field distributions, and measured transmission at oblique incidence. Furthermore, electric and magnetic resonances can be tailored by the geometrical parameters of the nanoplates. In a rectangular nanoplate, magnetic resonance only shifts with the width along the incident polarization, and electric resonance shifts obviously as the aspect ratio of the nanoplate changes. The investigation may provide a tunable building block for optical metamaterials. © 2010 IOP Publishing Ltd
