GEOMETRICAL EFECTS ON THE ABSORPTION OF MHD WAVES AT THE ALFVEN SPATIAL RESONANCE
Recent advances of MHD theory of Alfven Wave Heating have shown evidence of several novel features. These features are related to the inclusion of the Hall term and to the inclusion of shear and curvature of the magnetic field lines in cylindrical plasmas. It is important to ascertain the extent to which these features are retained in a simpler geometry such as a slab. We have employed a cold, current carrying plasma model for a slab of finite thickness, in order to compare results with those already obtained using other models. We show that some phenomena have similar behaviour in a slab plasma as in a cylindrical plasma. However, the general conclusion is that the slab geometry provides a qualitatively correct model for only some of the features relevant to Alfven Wave Heating.
