Multi‐Ion Oscillitons—Origin of Coherent Magnetospheric EMIC Waves
Journal of Geophysical Research: Space Physics, 2022 AbstractThe recent spacecraft observations by MMS and Van Allen Probes associated with electromagnetic ion cyclotron (EMIC) waves in the Earth magnetosphere emphasize the important role of multi‐ion plasma composition for generation and characteristics of these emissions. We show that main properties of the coherent EMIC waves can be explained with the

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 need detailed knowledge of the wave field’s spatio-temporal evolution, which cannot be obtained from

Physical mechanisms of compressional EMIC wave growth [PDF]
Journal of Geophysical Research: Space Physics, 2010 On 29 June 2007, electromagnetic ion cyclotron (EMIC) waves were observed on the ground by the Canadian Array for Realtime Investigations of Magnetic Activity (CARISMA) network of magnetometers between L = 4 and L = 6 in response to a significant magnetospheric compression.
