Abstract
AbstractPrevious studies have demonstrated that the propagation of whistler waves can be ducted by plasma density structures, within which the trapped waves can interact with electrons for a rather long time. In this paper, we develop a theoretical model to investigate the effects of magnetic structures on the propagation of whistler waves. Our results show that whistler waves can be ducted both in magnetic dips and peaks under specific conditions, providing another trapping mechanism for whistler waves. These theoretical predictions have been verified through two typical wave events observed by the Van Allen Probe mission based on the magnetic dip ahead of and magnetic peak inside a dipolarizing flux bundle. The theoretical analysis and satellite observations reveal the important role of magnetic structures in the propagation of whistler waves.
