AB: In a plasma consisting of at least two ion species with different charge-to-mass ratios, the existence of the ion-ion hybrid and Alfvén resonances will greatly modify the wave propagation characteristics around the ion cyclotron range of frequencies (ICRF). We investigate the problem of the wave propagation in two ion plasmas around the ICRF. We calculate the resonant absorption at the Buchsbaum-Bers ion-ion hybrid, the ion-ion hybrid and the Alfvén resonances in an exact manner by adopting the invariant imbedding method (IIM). With the IIM, we obtain quantitative and accurate values for simple dissipation and mode conversion, respectively, when fast waves are incident. The resonant absorption of fast waves becomes significant at the Buchsbaum-Bers ion-ion hybrid resonance only when the parallel wave number becomes relatively small. When the parallel wave number is relatively large, the fast waves tend to be dissipated at the ion-ion hybrid and the Alfvén resonances.
