Nonlinear characteristics of magnetic surface waves with microwave excitation
微波激发下非线性磁表面波传播特性

Properties of transverse electric surface waves on a plane interface between a linear ferromagnet and a nonlinear antiferromagnet are investigated. The dispersion relation and the field distribution are obtained. The property investigation of the surface waves in this waveguide shows that there exist passbands and stopbands, which can be controlled by varying the power in the nonlinear gyromagnetic waveguide. The results provide ideas to develop devices capable of working in microwave frequency range.
