The propagation of fast waves in the ion - cyclotron range of frequencies in the plasmas is investigated by using the ray - tracing method. The hot plasma dispersion relation is given with the thermal effect correction, and the ray trajectories are obtained by numerically resolving the ray equations which are integrated with the hot plasma dispersion relation under the initial injected waves parameters. It shows that, with the appropriate parameters, fast wave can easily propagate in the plasmas, reach the center position of the plasmas ,and be refle...
