Abstract

The purpose of this study is to investigate the effect of the presence of the mode conversion (nz<nzcritical), on the evolution of the electric field of the lower hybrid (LH) propagating wave. The propagation of the LH wave in a magnetized plasma, for both mode polarization (slow and fast), is described by a fourth order ordinary differential equation, which here has been analyzed analytically and numerically. A complete WKB solution of the 4th order equation has also been obtained showing the failure of the method near the cut-offs and the mode conversion point. © 2010 IOP Publishing Ltd.
