The nonlinear characteristics of TM surface waves at microwave frequencies in a layered structure of left-handed metamaterial filme, a nonlinear antiferromagnet cover, and a linear dielectric substrate have been performed. The complex wave number of TM surface wave is computed by solving the dispersion equation in order to find out the reduced phase and attenutation constants. The effects of the frequency and nonlinearity of antiferromagnet on the reduced phase and attenuation constants have been examined. The power flow has also been studied as a function of the reduced phase and attenuation constants.
