The propagation and absorption of the maser radiation emitted during solar flares are examined through linear theory and electromagnetic particle simulations. While linear theory predicts complete absorption of the maser radiation at the second harmonic layer (where the local cyclotron frequency is roughly one-half the frequency of the maser radiation), particle simulations indicate that some radiation escapes clue to reemission of absorbed energy by the ambient plasma. Strong perpendicular heating of the ambient electrons occurs as well.
