The effective response depends sensitively on composite microstructure due to large fluctuations in the local-electric field. For metallic clusters embedded in a dielectric host, the local-field distributions are extremely inhomogeneous in space around the metallic clusters due to quasistatic resonance, leading to a large enhancement in the effective linear and nonlinear responses. In this paper, we propose a general method for computing the electric field of metallic clusters near resonance via a perturbation formalism. We illustrate the method by simple examples.
