Abstract:

The set of linearized magnetohydrodynamic equations has been reduced to the reflectivity equation for the compressional magnetic perturbations in the framework of the Radoski model. It has been shown that the reflection coeficient is a function of the inhomogeneities of the magnetic field, and the inhomogeneities of the Alfven velocity. An interesting property of the reflectivity equation is that, near Alfven resonant magnetic force lines, this equation reduces to the curvature free Budden equation. Near Alfven resonances the curvature does not play a significant role and Buddens asymptotics in time can be applied to the wave field near the magnetic force lines where the Alfven dispersion relation holds.
