表面波传播在尘埃磁化等离子体中的频率低于和离子回旋频率的顺序，但远高于尘埃回旋频率，被认为是。尘埃颗粒被假定是静止的，但是携带了等离子体的一部分负电荷。本文导出并讨论了尘埃等离子体与真空界面上表面波传播的色散关系。推导了窄但非零宽度界面中由于阿尔芬共振吸收引起的波的阻尼。
Surface wave propagation in a dusty magnetized plasma at frequencies below and of the order of the ion‐cyclotron frequency, but well above the dust cyclotron frequency, is considered. The dust grains are assumed to be stationary, but to carry a proportion of the negative charge of the plasma. The dispersion relation for surface waves propagating on an interface between a dusty plasma and a vacuum is derived and discussed. The damping of the waves due to Alfven resonance absorption in a narrow but non‐zero width interface is derived.
