Anomalous absorption of electromagnetic wave energy near the lower hybrid resonance

V N Pavlenko, V G Panchenko, S M Revenchuk1984年Plasma Physics and Controlled FusionIF 2.2出版社

The influence of an RF pump wave on the spectral electric field fluctuation density and the value of the electromagnetic wave energy density, which is absorbed in the presence of parametric instabilities, is investigated. The RF field power which is absorbed in the plasma is estimated near the threshold of the decay instability. It is shown that the absorbed power increases anomalously as ln(Eth,12/E02-1) for the decay of pump wave into lower hybrid and ion-acoustic waves and as (Eth,22/E02-1)-1/2 for the decay of pump wave into lower hybrid wave and ion quasimode (Eth,1 and Eth,2 are the threshold electric field strength relatively to the excitation of the instabilities which are under consideration and E0 is the pump field strength).

RFポンプ波が、パラメトリック不安定性の存在下で吸収される電磁波エネルギーのスペクトル電場変動密度および値に及ぼす影響について調査する。RF場の電力が、崩壊不安定性の閾値近傍でプラズマ中に吸収される量を見積もる。吸収される電力は、ポンプ波が低混成波およびイオン音波へ崩壊する場合にはln(E_th,1^2/E_0^2-1)として、またポンプ波が低混成波およびイオン準モードへ崩壊する場合には(E_th,2^2/E_0^2-1)^(-1)として異常に増大することが示される(ここで、E_th,1およびE_th,2は、それぞれ考慮中の不安定性の励起に対する閾値電場強度であり、E_0はポンプ場強度である)。
