Observational Properties of Harmonic EMIC Waves: Statistical Study

open access: yesGeophysical Research Letters
Electromagnetic ion cyclotron (EMIC) waves are discrete electromagnetic emissions separated by multiple ion gyrofrequencies. Harmonic EMIC waves are defined as waves with a strong electric or magnetic field (or both) at the harmonics of the fundamental ...

Relativistic Electron Precipitation by EMIC Waves: Importance of Nonlinear Resonant Effects [PDF]

open access: yesGeophysical Research Letters, 2022
Relativistic electron losses in Earth's radiation belts are usually attributed to electron resonant scattering by electromagnetic waves. One of the most important wave modes for such scattering is the electromagnetic ion cyclotron (EMIC) mode. Within the

Occurrence Rates of Electromagnetic Ion Cyclotron (EMIC) Waves With Rising Tones in the Van Allen Probes Data Set. [PDF]

open access: yesJ Geophys Res Space Phys, 2023
In Fourier time‐frequency power spectrograms of satellite magnetic field data, electromagnetic ion cyclotron (EMIC) waves may feature discrete, rising tone structures that rapidly increase in frequency.

Amplitude Dependence of Nonlinear Precipitation Blocking of Relativistic Electrons by Large Amplitude EMIC Waves [PDF]

open access: yesGeophysical Research Letters, 2022
Recent work has shown that ElectroMagnetic Ion Cyclotron (EMIC) waves tend to occur in four distinct regions, each having their own characteristics and morphology.

Confirmation of EMIC wave driven relativistic electron precipitation [PDF]

open access: yesJournal 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,

Identification of ring current proton precipitation driven by scattering of electromagnetic ion cyclotron waves [PDF]

open access: yesFundamental 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 ...

Full‐wave modeling of EMIC waves near the He+ gyrofrequency [PDF]

open access: yesGeophysical 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 ...
