摘要
We present a two-fluid simulation of the interaction between the powerful HF (high-frequency) electromagnetic wave and the ionosphere. The OTSI (Oscillation Two-Stream Instability) and PDI (Parametric Decay Instability), near and below the turning point of ordinary wave mode respectively, are excited. The region of coexistence of OTSI and PDI is investigated. The spectral features in OTSI, PDI and coexistence area are studied. The wave conversion from O mode to Z mode is studied by using different source intensity.
