摘要: The effect of electron inertia on kinetic Alfven wave has been studied. expressions for the dispersion relation, growth/damping rate and length inertial (IKAW) are derived using approach in cusp region. Vlasov-kinetic theory adopted to evaluate with respect perpendicular number k⊥ρi (ρi is ion gyroradius) at different plasma densities. evaluated me/βmi, where β ratio pressure magnetic field pressure, mi, e mass electron, respectively, as I=me/βmi represent boundary between regimes. It observed that frequency ω decreasing density. polar an ideal laboratory studies nonlinear processes important understanding basic physics, well magnetospheric astrophysical applications these processes.
