Surface wave evolution in a waveguide with an axial plasma column upon changing the external magnetic field

S T Ivanov, E G Alexov, A T Bogdanov, P N Malinov1990年Plasma Physics and Controlled FusionIF 2.2出版社

The surface wave evolution in a waveguide with a plasma column upon changing the external longitudinal magnetic field from 0 to infinity is investigated. It is shown that a family of anisotropic plasma modes EHl1ap exists when the magnetic field has intermediate values. When Omega < omega p (where Omega is the cyclotron frequency and omega p the plasma frequency), the EHl1ap modes have a surface wave field distribution. When Omega > omega p, they exist only for some system parameters and their field distribution has a quasi-surface character and when kz to infinity (where kz is the longitudinal wave number), the fields have a volume wave distribution.

外部縦磁場を0から無限大まで変化させた場合の、プラズマ柱を有する導波管内の表面波発展について調査する。磁場が中間的な値をとるとき、異方性プラズマモードEHl1apの族が存在することが示される。Ω < ωp(ここでΩはサイクロトロン周波数、ωpはプラズマ周波数)の場合、EHl1apモードは表面波の電界分布を持つ。Ω > ωpの場合、それらは特定のシステムパラメータに対してのみ存在し、その電界分布は準表面波的性質を示し、kzが無限大に近づくとき(ここでkzは縦波数)、電界分布は体積波的分布となる。
