Ion cyclotron electromagnetic wave structure in Elmo bumpy torus
Journal of Plasma Physics, 1985The problem of ion cyclotron wave structure in EBT has been analyzed using the smallness of the inverse aspect ratio ε = a/R0 and of the inverse cavity number ε' = 1/N. The procedure is to expand in these two parameters, reducing the complete toroidal problem to a system of equations to be solved in sequence.

Electromagnetic ion cyclotron waves in the plasma depletion layer
Journal of Geophysical Research: Space Physics, 1993We have studied the theoretical properties of electromagnetic ion cyclotron (EMIC) waves which occur in the plasma depletion layer. Our analysis assumes a homogeneous plasma with the characteristics which were measured by the AMPTE/CCE satellite at 1450‐1501 UT on October 5, 1984. During this time, waves were observed in the Pc 1 frequency range (0.2‐5

Electromagnetic Ion Cyclotron Waves for Radiation Belt Remediation Applications
IEEE Transactions on Plasma Science, 2013The high-energy particles of the Van Allen belts coming from cosmic rays, solar storms, and man-made processes pose a risk to humans and spacecraft operating in those regions. These high-energy fluxes rapidly damage electronics, optics, and other systems.

A statistical study of auroral electromagnetic ion cyclotron waves
Journal of Geophysical Research: Space Physics, 1998This paper discusses results from a statistical study of narrowband auroral electromagnetic ion cyclotron (EMIC) waves recorded by the Freja magnetic field experiment from December 1, 1993, to November 30, 1994. The study involves data collected at all magnetic local times (MLT), invariant latitudes between 40° and 75°, and altitudes between 1200 and ...

Electromagnetic Ion Cyclotron Harmonic Waves Generated via Nonlinear Wave-Wave couplings
2022<p><strong>&#160;</strong>In 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.

Effects of wave superposition on the polarization of electromagnetic ion cyclotron waves
Journal of Geophysical Research: Space Physics, 1996Using data from the Active Magnetospheric Particle Tracer Explorers/Charge Composition Explorer spacecraft, we make a detailed comparison between the observed polarization properties of electromagnetic ion cyclotron (EMIC) waves and those predicted by theory.

Properties of quasi-periodical emission of electromagnetic ion cyclotron waves
2022<p>Energetic electron scattering by electromagnetic ion cyclotron (EMIC) waves is one of the most effective mechanisms of electrons losses in the inner magnetosphere. Such resonant scattering has been traditionally considered as a controlling process for the dynamics of relativistic electron fluxes in the Earth&#8217;s radiation ...

AbstractElectromagnetic ion cyclotron (EMIC) waves in duskside plasmasphere and plasmaspheric plume scatter megaelectron volt electrons into the loss cone and are considered a major loss mechanism for the outer radiation belt. Wave‐particle interaction between energetic electrons and EMIC waves has been studied extensively by the quasi‐linear diffusion

Instability of Electromagnetic Ion Cyclotron Harmonic Waves in Plasmas
IEEE Transactions on Plasma Science, 1975The stability of electromagnetic ion cyclotron harmonic waves propagating normal to an external magnetic field is studied for plasmas whose ions possess loss cone type velocity distributions. It is found that, if the ions are stationary, no instability develops except in the extreme case when the ratio of parallel to perpendicular "temperatures" of the

Scattering of ordinary electromagnetic waves by ion cyclotron waves in the ionosphere
Journal of Geophysical Research: Space Physics, 1979It is shown that an ordinary electromagnetic wave can excite parametric instability by scattering off electrostatic ion cyclotron waves. Application of our result in the European auroral zone of the ionosphere is discussed.
