摘要：
A full wave numerical method is developed for fast wave current drive in tokamak plasmas, in which finite Larmor radius effects and parallel dispersion are taken into account. A physical model with full wave are developed. Electric field distribution in radial is obtained. It shows that fast wave can propagate to central plasma; Mode conversion happened near central plasmas; Fast wave can drive current in centre to improve balance current profile; Parallel electric is weaker than that in vertical direction. The current is droven by Landau damping and transit-time magnetic pumping.
