报告内容: We have investigated solutions of the KMM system in two cases for s=0 and s≠0) by the CTE method and the Painlevé-Backlund transformation, for the case(s=0), the KMM system is integrable. There are many new type structures of solutions obtained., such as breather soliton, multipole instanton and rogue waves. Rogue waves have different structures including butterfly-type, X-type and Y-type ones. We also study in details the effects of Gilbert-damping and inhomogeneous exchange on the propagation of short waves in various saturated garnet ferrites. |
