The propagation of electromagnetic waves in magnetic metamaterials is studied. Magnetic metamaterials are composed of split-ring resonators (SRRs) whose capacitance shows nonlinearities and random fluctuations. Applying reductive perturbation analysis to time evolution equations for voltages in SRRs, the nonlinear Schrodinger equation with a stochastic term is derived. By taking the statistical average of a one-soliton solution, the deformation of a soliton during propagation due to microscopic disorder is investigated.
