Abstract
The oblique propagation of fast sausage and kink magnetohydrodynamic (MHD) surface waves in an ideal magnetized plasma slab in the low-β plasma limit is studied considering the Hall term in the generalized Ohm's law. It is found that the combining action of the Hall current and oblique wave propagation makes possible, for a given wave number , the existence of multivalued solutions to the wave dispersion relations. Some of wave solutions corresponding to positive values of the transverse wave number, ky, undergo a “stop band” at specific (numerically found) wave numbers. It also is shown that with wave-number increasing the waves change their structure–from bulk to pseudosurface, leaky or pure surface waves.
