Nonresonant Resistive Dissipation of Incompressible Magnetohydrodynamic Waves
Abstract
The influence of departures from homogeneity on the dissipative properties of incompressible MHD waves are examined within the framework of an analytically solvable model in plane geometry. Only resistive dissipation is taken into account. The existence of a new class of rapidly oscillating solutions is proved for which the role of resistivity is not restricted to a single narrow layer, as in the well-known resonating case, but extends to the whole system.
