II.RELATED WORKThe Earth's ionosphere is a cold, low β and weakly collisional plasma and can sustain plasma waves and instabilities
Perturbation develops in this open plasma system for the entry of energy and momentum fluxes through particles and waves and for some physical factors like solar wind, density gradients, magnetic field gradients and thermal gradients
We investigate the amplification of electrostatic high frequency ion sound wave in the presence drift instability on the basis of a wave-particle interaction process called plasma maser effect
Summary
The Earth's ionosphere is a cold, low β and weakly collisional plasma and can sustain plasma waves and instabilities. We investigate the amplification of electrostatic high frequency ion sound wave in the presence drift instability on the basis of a wave-particle interaction process called plasma maser effect. Nonresonant plasma wave is amplified at the cost of low frequency resonant mode wave energy This process occurs if there is a supply of free energy source likes energetic electrons flux or magnetic flux in the system. In this paper on the basis of plasma maser effect we present our theoretical investigation on amplification of ion sound wave in presence of low frequency drift turbulence in inhomogeneous ionospheric region. In this problem we want to study instability of ion sound wave on the basis of weak turbulence theory in the presence of low frequency drift wave turbulent field.
