Ray Direction in a Warm Electron Magnetized Plasma

摘要: 本文给出了暖电子等离子体中各种频率波的射线方向.揭示了射线方向矢量的一些重要特征.特别是当波在暖等离子体相应的冷等离子体谐振区附近,暖等离子体中有一个等离子体波在传播.电子等离子体波可以与寻常波或非常波相联接,并使波能比在一个相应冷等离子体中有更宽的传播角域.Abstract: The directions of the group-velocity vectors of waves of various frequencies in a warm-electrons only plasma are given. Some important properties of the direction of group-velocity vectors are revealed. It is shown in particular that there is a plasma wave propagating near the resonant region of the wave in the corresponding cold plasma. The electron plasma wave can link with the ordinary wave or the extraordinary waves. This makes waves capable of propagating in a broader range of angles than in a corresponding cold plasma.
