【摘要】 针对波矢ｋ与外偏置磁场Ｈ０成任意角度的静磁表面波提出了传播截止角的概念，给出了依赖于强度的非线性色散方程，研究揭示了线性和非线性静磁表面波能流方向受Ｈ０方向控制在０￣９０°范围内可调的特性．更多还原

【Abstract】 A concept of propagation cut-off angle of magnetostatic surface wave (MSSW) is put forward and formulated. The nonlinear dispersion relation of MSSW is given and the new characteristics of the tunable energy flow direction of linear and nonlinear MSSW are presented in this paper.更多还原
