Nonlinear TM surface waves in a single interface of antiferromagnet and left-handed metamaterial structure

In this paper, nonlinear TM surface wave have been studied theoretically in a single interface of antiferromagnet and LH metamaterial. The complex wave number of TM surface wave is computed by solving the dispersion equation in order to find out reduced phase and attenuation constants. The effects of operating angular frequency (/spl omega/), and non-linearity of antiferromagnet on reduced phase and attenuation constants have been examined. The power flow has also been studied as a function of reduced phase and attenuation constants.
