Author ProfileAbstract
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.16 May 2024Submitted to ESS Open Archive 21 May 2024Published in ESS Open Archive
