Full‐wave modeling of EMIC waves near the He+ gyrofrequency [PDF]
Geophysical Research Letters, 2016 Electromagnetic ion cyclotron (EMIC) waves are known to be excited by the cyclotron instability associated with hot and anisotropic ion distributions in the equatorial region of the magnetosphere and are thought to play a key role in radiation belt ...

Identification of ring current proton precipitation driven by scattering of electromagnetic ion cyclotron waves [PDF]
Fundamental Research, 2023 Among the most intense emissions in the Earth's magnetosphere, electromagnetic ion cyclotron (EMIC) waves are regarded as a critical candidate contributing to the precipitation losses of ring current protons, which however lacks direct multi-point ...

Oxygen torus and its coincidence with EMIC wave in the deep inner magnetosphere: Van Allen Probe B and Arase observations [PDF]
Earth, Planets and Space, 2020 We investigate the longitudinal structure of the oxygen torus in the inner magnetosphere for a specific event found on 12 September 2017, using simultaneous observations from the Van Allen Probe B and Arase satellites. It is found that Probe B observed a

A statistical study of EMIC waves observed by Cluster: 1. Wave properties [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractElectromagnetic ion cyclotron (EMIC) waves are an important mechanism for particle energization and losses inside the magnetosphere. In order to better understand the effects of these waves on particle dynamics, detailed information about the occurrence rate, wave power, ellipticity, normal angle, energy propagation angle distributions, and ...

Full-wave modeling of EMIC wave packets: ducted propagation and reflected waves
Frontiers in Astronomy and Space Sciences, 2023 Electromagnetic ion cyclotron (EMIC) waves can scatter radiation belt electrons with energies of a few hundred keV and higher. To accurately predict this scattering and the resulting precipitation of these relativistic electrons on short time scales, we ...

EMIC wave parameterization in the long‐term VERB code simulation [PDF]
Journal of Geophysical Research: Space Physics, 2017 AbstractElectromagnetic ion cyclotron (EMIC) waves play an important role in the dynamics of ultrarelativistic electron population in the radiation belts. However, as EMIC waves are very sporadic, developing a parameterization of such wave properties is a challenging task.
