Abstract Text:
The effects of turbulent diffusion on a temporal mode of surface waves propagating at the interface of turbulent plasmas are investigated. The damping rates for high and low-modes of surface wave are kinetically derived by employing the Vlasov-Poisson equations and the specular reflection boundary condition. We found that the diffusion caused by the fluctuating electric fields leads to damping for both high and low-modes of surface waves. The high-mode damping is enhanced with an increase of the wave number and the diffusion coefficient, but suppressed by an increase of electron thermal energy. In contrast, the low-mode damping is suppressed as the wave number and the thermal energy increase although it is enhanced as the diffusion increases.
