Abstract:- Electromagnetic ion-cyclotron (EMIC) waves have been studied by single particle approach. The effect of kappa distribution function on EMIC waves at different plasma particle densities, the dispersion relation, growth length, growth rate, parallel and perpendicular resonance energy of electromagnetic ion cyclotron waves in low β (ratio of plasma pressure to magnetic pressure) homogeneous plasma have been obtained. The effect of steepness of the kappa distribution and density has been studied of the ions. In these studies, we have presented some previous work but different investigation of kappa distribution function on EMIC waves in cold plasma. The dispersion relation, particle densities, growth rate and growth length of the EMIC waves are derived 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 kappa distribution function with plasma densities is to enhance the wave growth of EMIC waves with ions. The results are interpreted for the space plasma parameters appropriate to the auroral acceleration region of the earth magneto plasma.
