Abstract

Generalised ray theory provides a simple description of MHD mode transmission and conversion between magnetoacoustic fast and slow waves and is directly applicable to solar active regions. Here it is tested in a simple two-dimensional, isothermal, gravitationally stratified model with inclined magnetic field using previously published exact solutions and found to perform very well.
