In this paper mode conversion of the ordinary wave to the extraordinary wave in a cold magnetized plasma at electron cyclotron frequencies is examined. A reduced set of wave equations, accounting for both the 2D inhomogeneity of the magnetic field and an arbitrary poloidal component of the magnetic field and coupling of the ordinary wave to the extraordinary wave near the O-mode cutoff surface, is derived. An integral representation of solutions to this set of equations is found. The conversion and reflection coefficients are calculated and analysed.
本論文では、冷たい磁化プラズマ中の電子サイクロトロン周波数における常波から異常波へのモード変換を考察する。磁場の2次元不均一性と磁場の任意のポロイダル成分の両方を考慮した簡約波動方程式系を導出する。この方程式系の解の積分表示を求める。変換係数と反射係数を計算し、解析する。
