摘要：

The electromagnetic drift instability leading to the excitation of the Alfven waves in an axially inhomogeneous plasma is investigated. The instability is driven by the axial shear of the ExB drift velocity maintained by the localized density gradient. Analytical dispersion relation has been derived in the short wavelength (WKB) limit. The eigenvalue problem has also been solved numerically by using the recently developed algebraic method.
