The parametric interaction of electromagnetic waves in a medium with a negative index of refraction is considered. Two cases of Kerr and quadratic nonlinearities are investigated. The properties of nonlinear coupler, channels of which made of material with opposing signs of refraction index, are studied. Dynamics of extremely short pulses in the homogeneous doubly-resonant medium is analyzed in the framework of Maxwell-Duffing-Lorentz model. The new type of quasi-solitons is presented.
