Disordered RL С networks are known to be an adequate model for describing fluctuations of electric fields in a random metal-dielectric composite. We show that under appropriate conditions the statistical properties of such a system can be studied in the framework of the Efetov's non-linear σ-model. This fact provides a direct link to the theory of Anderson localization.
