Langmuir Wave energy upconversion in presence of Lower Hybrid Wave turbulence in Polar Ionospheric Plasma

Abstract

In the Earth's ionosphere wide range of instabilities are observed due to presence of free energy sources. Wave-wave and wave-particle interaction processes may take place here. Through wave-particle interaction process wave energy can be pumped up from the system for amplification of high frequency non-resonant wave where low frequency turbulence is present. In this study we have considered ionosphere as homogeneous medium and wish to investigate probable amplification of nonresonant Langmuir wave in the presence of resonant Lower hybrid wave through nonlinear wave-particle interaction. We have estimate growth rate of Langmuir wave using satellite observational data.
