dc.description.abstractElectromagnetic ion-cyclotron (EMIC) waves have been studied by single particle approach. The effect of ion beam on EMIC instability in the presence of parallel electric field at different plasma densities is evaluated. The dispersion relation, growth rate parallel and perpendicular resonance energies of the electromagnetic ion-cyclotron waves in a low b (ratio of plasma pressure to magnetic pressure), homogeneous plasma have been obtained. The wave is assumed to propagate parallel to the static magnetic field. The whole plasma is considered to consist of resonant and non-resonant particles. It is assumed that resonant particles participate in energy exchange with the wave whereas; non-resonant particles participate in the oscillatory motion of the wave. The effect of ion beam on EMIC waves in the presence of parallel electric field at different plasma densities is to enhance the growth rate of EMIC waves. The results are interpreted for the space plasma parameters appropriate to the auroral acceleration region of the earth’s magneto-plasma.en_US
