Resumen:
We investigate the existence of MHD leaky waves in compressible and layered plasmas. We consider perturbations of complex frequency in a slab model of three layers. We develop a general method that includes the cubic modes as well as other kinds of leaky waves, and allows to derive many results in closed form. There are several physical mechanisms that can produce leakage. We show two numerical example to exhibit the different behaviours that can arise. Finally we comment the connection of the present results with those obtained by other authors and correct some errors.
