A RF code named ‘hybrid’ for heating problem of mirror confinement machine is developed. The meaning of the hybrid is that the heating problem is solved partially by analytic and partially by numerical method without loss of generality. The vacuum region including an antenna current is dealt with analytic technique and usual FDM for the plasma region. In this work we propose proper boundary conditions of electric field on the axis of cylinder. We applied this method to solving the heating problem of HANBIT the mirror confinement machine located at the KBSI site. The dispersion characteristics are studied by calculating antenna radiation resistance for variance of external magnetic field strength and plasma density and also compared with the experimental data. The heating and field profiles are also investigated for given magnetic and density configurations. © 2003 American Institute of Physics
