Description

The coupled radial eigenmode equations for electromagnetic drift waves in a sheared magnetic field are solved numerically. In addition to the familiar drift eigenmodes, a different set of eigenmodes was found which is the analog of the sheared Alfven waves of local theory in a sheared magnetic field. The drift mode is mainly electrostatic, and the shear Alfven mode is mainly electromagnetic and closely related to the high-order tearing modes
