Electromagnetic ion-cyclotron (EMIC) waves have been studied using the kappa distribution function by investigating the trajectory of charged particles and using the method of particle aspect analysis. In these studies, we have investigation of kappa distribution function on EMIC waves in cold magnetized plasma. It is a region of dense, cold plasma that surrounds the earth magnetosphere. The dispersion relation, perpendicular and parallel resonant energies ( Wr & WrП), growth rate (γ) and growth length (Lg) of the EMIC waves is derived. The EMIC waves propagate parallel as well as oblique to the magnetic field. The whole plasma is considered to consist of resonant and non-resonant particles. It is assumed resonant particles participate in energy exchange with the wave, whereas non- resonant particles participates in the oscillatory motion of the wave3. The results are interpreted for the space plasma parameter appropriate to the auroral acceleration region in magnetosphere.
