Through one-dimensional propagation theory, recent studies have demonstrated that chorus waves can be ducted not only by density structures, but also by magnetic peaks. However, such a ducting propagation in the inner magnetosphere has not been verified yet. In this study, we perform ray tracing simulations to investigate the two-dimensional propagation of chorus waves in magnetic peaks. It is found that chorus waves indeed can be ducted by the magnetic peak via repetitive reflections in both sides, similar to that of one-dimensional propagation theory. The physical mechanism for these repetitive reflections has also been discussed. Furthermore, parameter analysis has been implemented to show the effect of wave frequencies and incidence positions on the propagation of chorus waves. Our results will be helpful in improving the understanding of the duct propagation for whistler waves in the magnetosphere.
