  • 本文采用随机模型,讨论等离子体边界层密度涨落对低混杂波的散射。色散关系中考虑了电磁项及E×B对流项。结果表明:考虑电磁效应之后,低混杂波的透射率(透过密度涨落层进入等离子体中心区的波强度与入射波强之比)减小,而反射率增加。

     

    Making use of the stochastic model, we have studied the low-hybrid wave scattering by the density fluctuations in the edge-regions of Tokamak plasmas. The dispersion relation under consideration includes not only the E×B convective derivation term but also the electromagnetic correction term. The results show that the transmission coefficient decreases, whereas the reflection coefficient increases when the electromagnetic effect is taken into account.
