Oscillations of a rarefied plasma confined by a high-frequency field

V.V. Vaskov, V.I. Karpman1971年被引用 1Nuclear FusionIF 3出版社

The authors investigate the non-linear excitation of ion-acoustic oscillations in a plane plasma layer contained by an external high-frequency electromagnetic field of the TE wave type. The plasma is assumed to be collision-free and non-isothermal (Te » Ti). The time-averaged density distribution in the plasma layer is found. The conditions are ascertained for the resonance excitation of ion-acoustic waves at the second harmonic of the external field; near the resonance, the amplitudes of the excited waves can be fairly large, not only within the skin layer but also through the entire plasma volume.

著者らは、TE波型の外部高周波電磁場によって閉じ込められた平面プラズマ層におけるイオン音響振動の非線形励起を調査する。プラズマは無衝突かつ非等温(Te » Ti)であると仮定される。プラズマ層内の時間平均された密度分布が求められる。外部場の第二高調波におけるイオン音響波の共鳴励起の条件が確認される;共鳴近傍では、励起された波の振幅は、表皮層内だけでなくプラズマ全体の体積を通してもかなり大きくなり得る。
