“…In this limit, the spatial scale that defines a "small" perpendicular wavelength is the ion sound gyroradius, q s ¼ c s =x ci , where x ci ¼ eB 0 =m i c is the ion cyclotron frequency and c s ¼ (k B T e =m i ) 1=2 is the ion sound speed, with e being the charge of an electron, k B is Boltzmann's constant, m e is the electron mass, and c is the speed of light. 11 For electron thermal speeds less than the Alfvén speed, electron inertia becomes important and the wave is referred to as an "inertial Alfvén wave (IAW)." In this limit, the relevant "small" spatial scale is the electron skin depth, d e ¼ c=x pe , where x pe ¼ (4pn e e 2 =m e ) 1=2 and n e is the electron density.…”

“…This wave is the electrostatic limit of the shear Alfvén wave, 24,25 which lies in the regime of inertial Alfvén waves. 26,27 The difficulties introduced by such a wave could be eased by including magnetic perturbations from A , in which case the dispersion relation (in the fluid electron regime ξ 1) becomes…”
