【Abstract】 The characteristics of nonlinear surface electromagnetic TM waves propagating at the interface of antiferromagnetic crystal and a superlattice were studied. The dispersion relation of the wave was given and the influence of the angle θ of the liquid crystal orientation in the superlattice on the propagation of the wave was studied. In was found, when this wave exists in the waveguide the θ must be 0 or π /2. Numerical analysis of the frequency characteristics of the nonlinear TM waves was made through the field distribution pictures.更多还原
