Trapping and Amplification of Unguided Mode EMIC Waves in the Radiation Belt [PDF]
Journal of Geophysical Research: Space Physics, 2021 Abstract Electromagnetic ion cyclotron (EMIC) waves can cause the scattering loss of the relativistic electrons in the radiation belt. They can be classified into the guided mode and the unguided mode, according to wave's propagation behavior.

Confirmation of EMIC wave‐driven relativistic electron precipitation [PDF]
Journal of Geophysical Research: Space Physics, 2016 AbstractElectromagnetic ion cyclotron (EMIC) waves are believed to be an important source of pitch angle scattering driven relativistic electron loss from the radiation belts. To date, investigations of this precipitation have been largely theoretical in nature, limited to calculations of precipitation characteristics based on wave observations and ...

On the variability of EMIC waves and the consequences for the relativistic electron radiation belt population [PDF]
, 2021 The interactions between electromagnetic ion cyclotron (EMIC) waves and relativistic electrons are influential in diffusing radiation belt electrons into the loss code from which the electrons are lost into the atmosphere.

Occurrence of EMIC Waves in the Magnetosphere According to Their Distance to the Magnetopause [PDF]
Geophysical Research Letters, 2021 AbstractWave growth of electromagnetic ion cyclotron (EMIC) emissions observed in the outer magnetosphere is mainly controlled by compression events resulting from solar wind dynamic pressure pulses. During such events wave growth is expected to be maximum close to the magnetopause. In previous studies, distribution of EMIC waves was analyzed according

On the Observation of Electrostatic Harmonics Associated With EMIC Waves [PDF]
Geophysical Research Letters, 2019 AbstractIn this study, we report two events of electrostatic harmonics associated with electromagnetic ion cyclotron (EMIC) waves recorded by the Van Allen Probes. Based on the wave and plasma measurements, the wave features are investigated and the possible generation mechanism is discussed.
