Abstract

A simple formula derived from the strong permittivity fluctuation theory (SPFT) is shown to provide a correction to the Bruggeman formalism for isotropic, cubically nonlinear, composite mediums by making use of the correlation length, a second-order statistic of the distribution of the two component material phases. The larger the correlation length, the larger are the differences between the estimates of the linear and the nonlinear dielectric properties of the homogenized composite medium provided by the two formalisms. The SPFT predicts attenuation and downgrades the possibility of nonlinearity enhancement, relative to the Bruggeman formalism.
