Determining EMIC Wave Vector Properties Through Multi-Point Measurements: The Wave Curl Analysis. [PDF]
J Geophys Res Space Phys, 2021 AbstractElectromagnetic ion cyclotron (EMIC) waves play important roles in particle loss processes in the magnetosphere. Determining the evolution of EMIC waves as they propagate and how this evolution affects wave‐particle interactions requires accurate knowledge of the wave vector, k.

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 ...

Confirmation of EMIC wave driven relativistic electron precipitation [PDF]
Journal of Geophysical Research: Space Physics, 2016 Electromagnetic 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,

Ionospheric Plasma Density Oscillation Related to EMIC Pc1 Waves [PDF]
Geophysical Research Letters, 2020 AbstractWe report the first observation of plasma density oscillations coherent with magnetic Pc1 waves. Swarm satellites observed compressional Pc1 wave activity in the 0.5–3 Hz band, which was coherent with in situ plasma density oscillations. Around the Pc1 event location, the Antarctic Neumayer Station III (L ~ 4.2) recorded similar Pc1 events in ...
