External excitation, propagation, and ion heating on the ion Bernstein wave (IBW) are studied for the single ion and two-ion species plasmas, using the particle simulation. It is found that the value of ω/Ω_i near the antenna position influences the excitation characteristics of the IBW. The wavelength and the group velocity of the propagating IBW agree well with those calculated from the linear dispersion relation. Corresponding to the experiment done at JIPP T-IIU, 3Ω_D heating process in the plasma composed of deuterium-like and hydrogen-like ions is investigated. The wave energy is deposited into the bulk and tail of the deuterium-like ions due to the third harmonic cyclotron resonance and the bulk of the hydrogen-like ions due to the 3/2Ω_H cyclotron subharmonic resonance, respectively. It is also discussed on the possibility that the heating efficiency may not depend on the concentration of the deuterium-like ion in the 3Ω_D heating in the actual tokamak experiment.
