| Abstract: | The effective nonolinear response of random composites, in which one or more components are nonlinear between with current density and electric field intensity, has been investigated. A method of mean-field approximation is applied to the investigation of weakly nonlinear random composites. The influences of microstructure and nonlinear exponent on the macroscopic properties are studied in detail. |
