Abstract
The properties of the nonlinear TM waves on the interface between a dielectric and an antiferromagnet are studied. The relationship between the field components of TM wave is discussed in detail, and the dispersion characteristics as well as the position of the peak field are exposed. The theoretical analysis shows that for the nonlinear TM waves there exist passband(s) and stopband(s) which can be switched into each other by varying the power. It is revealed that, in the case of\(\varepsilon _1 > \varepsilon _2 \), the nonlinear TM waves on the interface are backward surface waves with the group and phase velocities opposite.
