We investigate the characteristics of magneto-acoustic surface waves propagating at a single density interface, in the presence of an inclined magnetic field. For linear wave propagation, the dispersion relation is obtained and analytical solutions are derived for small inclination angle. The inclination of the field renders the frequency of the waves complex, where the imaginary part describes wave attenuation, due to lateral energy leakage.

倾斜磁场不连续处泄漏 MHD 波的传播

我们研究了在存在倾斜磁场的情况下在单密度界面传播的磁声表面波的特性。对于线性波传播，获得色散关系并推导出小倾角的解析解。由于横向能量泄漏，场的倾斜使波的频率变得复杂，其中虚部描述了波的衰减。
