We identify a new class of surface waves that arise at a plasma-liquid interface due to resonant coupling between discrete plasma pattern modes and a continuum of interfacial liquid surface wave modes. A wave mode is selected due to localized excitation by the plasma, and standing waves result when waves excited from different locations interact. These waves propagate with a slower phase velocity than traditional capillary waves, but exhibit the same damping behavior with respect to liquid viscosity. Surface tension does not appear to play a significant role. We propose a curvature-dependent Maxwell pressure mechanism to explain these nondispersive interfacial waves in the presence of plasma.

由于液体表面等离子体模式的界面耦合而产生的非毛细管波动力学

我们确定了由于离散等离子体模式与界面液体表面波模式的连续体之间的共振耦合而在等离子体-液体界面处出现的一类新的表面波。由于等离子体的局部激发而选择波模式，当从不同位置激发的波相互作用时会产生驻波。这些波以比传统毛细波慢的相速度传播，但在液体粘度方面表现出相同的阻尼行为。表面张力似乎没有发挥重要作用。我们提出了一种曲率相关的麦克斯韦压力机制来解释等离子体存在下的这些非色散界面波。
