我们研究了磁声表面波在倾斜磁场存在下在单一密度界面上传播的特性。对于线性波传播，得到了色散关系，并导出了小倾角下的解析解。由于侧向能量泄漏，场的倾斜使波的频率变得复杂，其中虚部描述了波的衰减。
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.
