Symmetrical electromagnetic waves in partially-filled plasma waveguide

S T Ivanov, E G Alexov, P N Malinov1989年Plasma Physics and Controlled FusionIF 2.2出版社

The electromagnetic waves in a partially-filled plasma waveguide, placed in an external d.c. magnetic field are numerically and experimentally investigated. Compared with the homogeneous filled waveguide, two new effects are observed. The inhomogeneous structure improves the cyclotron mode resolution. When the plasma filling of the waveguide is decreased, the coupling of both the EH and HE high-frequency modes with the cyclotron modes is possible. It is shown experimentally that increasing both the magnetic field and the discharge current (i.e. the plasma density) improves the cyclotron mode resolution.

外部直流磁場中に置かれた部分充填プラズマ導波管内の電磁波を数値的および実験的に調査した。均一充填導波管と比較して、2つの新しい効果が観測された。不均一構造はサイクロトロンモード分解能を向上させる。導波管のプラズマ充填率を低下させると、EHおよびHE高周波モードの両方とサイクロトロンモードとの結合が可能になる。磁場と放電電流(すなわちプラズマ密度)の両方を増加させると、サイクロトロンモード分解能が向上することが実験的に示された。
