波在暖电离层中的传播和耦合

本文研究了波在暖电离层中的传播。文中导出了用拆射率n表示的波的色散关系,并由此推导出分层暖电离层中q的方程。所有这些方程都被用于用射线方法研究波在暖电离层中的传播,模式联接和波的线性耦合。 本文还讨论了波方程的奇点、等离子体波与电磁波的耦合。在波耦合区中,波的场可以通过求解波方程在奇点附近的解而求得。文中比较了用射线方法和全波方程研究波耦合时电波传播的结果。 本文所得结果对研究用无线电波加热电离层实验中的吸收区域是有用的。

THE WAVE PROPAGATION AND THE MODE COUPLING IN THE WARM IONOSPHERE

The wave propagation in the warm ionosphere is studied in this paper. The dispersion relation of refractive index (n) of the waves is derived and the equation of q in the warm stratified ionosphere is inferred. All these equations have been used in studying of wave propagation, wave mode linking and linear mode coupling of the waves in the warm ionosphere by ray traeing method.The singular point of the wave equation and the coupling between the plasma waves and the electromagnetic waves are discussed. The wave field in coupling region can be got by solving the wave equation in the region near the singular point. The method of ray tracing and the method of wave equation were compared. The results of this paper could be useful in studying the absorption region of the ionosphere in the ionosphic heating experiment.
