N2 - The ac magnetoelectric properties of a metal-dielectric composite are considered in the quasistatic regime. When the metal constituent is not in the form of a dilute suspension, the magnetoplasma resonances are altered in a way that reflects the microstructure. When the microstructure is periodic with more than one characteristic length scale, the electric permittivity can exhibit a strong dependence on both the magnitude and the direction of the applied dc magnetic field. This will occur in the vicinity of one of those resonances if ωτ > 1. The possibility of observing this effect in a suitably synthesized composite film is considered in detail.
