| Abstract: | The Galerkin method is applied to investigate the effeCtive conductivity of strongly nonlinear composite media. In order to outline the method clearly, the system in which both the host and inclusion have a cubic nonlinearity is studied. Only the lowest order term in mode expansion is retained, and an approximate analytic formula for nonlinear effective conductivity of cubic nonlinear composite media is derived. |

| Keywords: | strongly nonlinear composite madia Galerkin method effective conductivity |
