In this paper, starting with the Maxwell equations and corresponding nonlinear wave equation, we derive a pulse evolution equation for metamaterial cubic (Kerr) nonlinearity. The given model goes beyond commonly employed slowly evolving approximation (SEWA). dispersive properties of dielectric susceptibility magnetic permeability are accounted in accordance Drude model. Using propagation single-cycle 4-cycle studied numerically left-handed (LHMM) third-order
