Parametric coupling of a high‐frequency electromagnetic wave to whistler and lower‐hybrid waves in the ionosphere

Parametric coupling of a high‐frequency electromagnetic wave to an obliquely propagating whistler or lower‐hybrid wave and a high‐frequency sideband electromagnetic wave have been studied in the ionosphere. The growth rate of the three‐wave resonant interaction process decreases with the frequency o...

Zusammenfassung:Parametric coupling of a high‐frequency electromagnetic wave to an obliquely propagating whistler or lower‐hybrid wave and a high‐frequency sideband electromagnetic wave have been studied in the ionosphere. The growth rate of the three‐wave resonant interaction process decreases with the frequency of the lower‐hybrid wave and increases with whistler wave frequency. Growth rate is greater for the whistler wave than the lower‐hybrid wave. The electromagnetic wave is scattered at a larger angle in the case of the lower‐hybrid wave than the whistler wave.
