Magnetohydrodynamical leaky waves in a layered plasma

We investigate the existence of MHD leaky waves in compressible and layered plasmas. We consider perturbations of complex frequency in a slab model with three layers. We develop a general method that includes the 'cubic modes' as well as other kinds of leaky waves, and allows us to derive...
