摘要：
The linear behaviors of kinetic and inertial Alfven waves (KAW/IAW) in a sheared magnetic field are investigated via a finite-mass fluid electron model in finite-beta magnetized plasmas. It is found that the KAW and IAW propagate in opposite directions after mode conversion. Here, beta is the ratio between plasma and magnetic pressures. The KAW propagates to the singular surface and deposits energy at the resonant point, where the wave resonates with the local electron motion. The IAW propagates away from the singular surface.
