Abstract

Electromagnetic ion-cyclotron (EMIC) waves have been studied by single particle approach. The dispersion relation, growth rate of the electromagnetic ion-cyclotron waves in a low β (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 effect of general loss-cone distribution function on EMIC waves is to enhance the growth rate. The results are interpreted for the Saturn magnetosphere has been applied to the magnetosphere Saturn to the observations made by Cassini parameters appropriate to the magneto-plasma.
