Modulation of Magnetosonic Waves by Background Plasma Density in a Dipole Magnetic Field: 2-D PIC Simulation 

Sun, Jicheng; Lu, Quanming; Wang, Xueyi; Liu, Xu; Gao, Xinliang; Yang, Huigen; 0000-0002-7211-0546; 0000-0003-3041-2682 (2022-11-08)
Recent satellite observations, combined with instability analyses, have shown that the background plasma density variation can modulate the magnetosonic (MS) waves by controlling the wave excitation. However, the detailed ...

Spectral properties and associated plasma energization by magnetosonic waves in the Earth's magnetosphere: Particle-in-cell simulations

Two-Dimensional Particle-in-Cell Simulation of Magnetosonic Wave Excitation in a Dipole Magnetic Field 

Chen, Lunjin; Sun, Jicheng; Lu, Quanming; Wang, Xueyi; Gao, Xinliang; Wang, Dedong; Wang, Shui (2020-05-27)
The excitation of magnetosonic waves in the meridian plane of a rescaled dipole magnetic field is investigated, for the first time, using a general curvilinear particle-in-cell simulation. Our simulation demonstrates that ...

Wave Normal Angle Distribution of Magnetosonic Waves in the Earth's Magnetosphere: 2-D PIC Simulation 

Sun, Jicheng; Chen, Lunjin; Wang, Xueyi; 0000-0002-5059-5394; 0000-0003-2489-3571 (2022-10-11)
Radiation belt electrons can be accelerated and scattered by magnetosonic waves in the Earth's magnetosphere, and the scattering rate of electrons is sensitive to the wave normal angle. However, observationally it is ...
