Abstract: The dielectric tensor, modified plasma dispersion function and dispersion relations for whistler mode instability are obtained for a generalized kappa distribution function in the presence of perpendicular a.c. electric field. Integrals and modified plasma dispersion functions are reduced to series form. Numerical methods using computer techniques are used to obtain temporal growth rate for a magnetospheric plasma. The results have been compared with observed GEOS1 and GEOS2 satellite data and HF generated whistler wave in polar electrojet region. The potential application for planetary atmosphere is also indicated.
