Abstract

Electromagnetic electron cyclotron (EMEC) waves have been studied for general loss-cone distribution function with temperature anisotropy around plasma-pause region. Electromagnetic electron cyclotron (EMEC) waves have been studied by kinetic approach. The effect of general loss-cone distribution function with temperature anisotropy on EMEC instability is evaluated the dispersion relation, growth rate. The main objective of the present investigation is to examine the effect of general loss-cone distribution index J with temperature anisotropy in view of the plasma-pause region. It is observed that the effect of increasing the distribution index is to increase the growth rate. The results are interpreted for the space plasma parameters appropriate to the plasma-pause region in magneto-plasma.
