Modelling the impact of energetic electrons on electron-acoustic instabilities and HF/UHF wave propagation in the ionospheric-like plasmas

Key Points

• Electron-acoustic instabilities affect the efficiency of HF and UHF wave propagation in the ionosphere.
• The model forecasts that 60% of wave attenuation is influenced by energetic electrons in ionospheric conditions.
• Simulation analysis across various plasma densities reveals the intricate dynamics between energetic electrons and wave interactions.
• Findings call for enhanced models to better predict wave behavior in real-world ionospheric scenarios.
