If we want to study the transfer of energy by waves through a stellar atmosphere, we first need to know its reflectivity with respect to each of the three MHD modes. Here, we will consider linear Alfvén waves only. The problem is set as follows. An energy flux being given at the bottom (z=0) of the atmosphere, we ask for how much of it is recorded at an altitude z.
