Abstract

The AC magneto-electric properties (including Faraday rotation, etc.)of a metal-dielectriccomposite are considered in the quasi-static regime.Resonances appear at modified values of the surface plasmon and cyclotronfrequencies, which depend on the applied magnetic field as well as on the microstructure.Whenthe microstructure is periodic and has more than one characteristic lengthscale, the electric permittivity can exhibit a strong dependence on boththe magnitude and the direction of the applied DC magnetic fieldin the vicinity of one of those resonances.The possibility of observing this effect in a suitably fabricatedcomposite film is discussed.
