Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath

Geophysical Research Letters
Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths.

MMS Measurements and Modeling of Peculiar Electromagnetic Ion Cyclotron Waves

Geophysical Research Letters, 2019
AbstractOrbiting Earth's dayside outer magnetosphere on 29 September 2015, the Magnetospheric Multiscale (MMS) satellites measured plasma composition, simultaneous electromagnetic ion cyclotron waves, and intermittent fast plasma flows consistent with ultralow frequency waves or convection.

Inner Magnetospheric Oxygen Torus Induced by Electromagnetic Ion Cyclotron Waves

Geophysical Research Letters
Cold oxygen ions escaping from the ionosphere and temporarily trapped near the plasmapause form the oxygen torus. Mass‐loading by these oxygen ions significantly affects magnetospheric plasma processes.

Proton aurora and relativistic electron microbursts scattered by electromagnetic ion cyclotron waves

Frontiers in Astronomy and Space Sciences, 2022
Charged particle precipitation from Earth’s magnetosphere results in stunning displays of the aurora and energy transfer into the atmosphere. Some of this precipitation is caused by wave-particle interactions.

Conjugate observations of electromagnetic ion cyclotron waves [PDF]

Journal of Geophysical Research: Space Physics, 2001
We compare electromagnetic ion cyclotron (EMIC) waves observed by the electric field instrument on Polar to simultaneous Pc1 pulsations detected at the subauroral Sodankylä station. We studied 44 passes where Polar was within ±1.5 hours in magnetic local time (MLT) from Sodankylä during a Pc1 pulsation event. In 70% of these passes a matching EMIC wave

Generation of O-Mode in the Presence of Ion-Cyclotron Drift Wave Turbulence in a Nonuniform Plasma

East European Journal of Physics, 2023
This study aims to investigate the effect of ion-cyclotron drift wave turbulence on the generation of ordinary mode (O-mode) in the presence of density and temperature gradients.

Electromagnetic Ion Cyclotron Harmonic Waves Generated via Nonlinear Wave‐Wave Couplings

Geophysical Research Letters, 2022
AbstractIn this letter, we report an electromagnetic ion cyclotron (EMIC) harmonic event observed by the Van Allen Probe B, whose generation is demonstrated to result from nonlinear wave‐wave resonances through the bicoherence analysis. Hybrid simulation shows that the second to sixth harmonics could be excited in sequence after a pump EMIC wave is ...
