On the breaking of a plasma wave in a thermal plasma. II. Electromagnetic wave interaction with the breaking plasma wave [PDF]
Physics of Plasmas, 2012 In thermal plasma, the structure of the density singularity formed in a relativistically large amplitude plasma wave close to the wavebreaking limit leads to a refraction coefficient with discontinuous spatial derivatives. This results in a non-exponentially small above-barrier reflection of an electromagnetic wave interacting with the nonlinear plasma

Radio emissions of auroral origin observable at ground level: outstanding problems
Frontiers in Astronomy and Space Sciences, 2023 Auroral radio emissions are of intrinsic interest as part of the Earth’s environment but also provide remote sensing of ionospheric conditions and processes and a laboratory for emission processes applicable to a wide range of space and astrophysical ...

Frontiers in Astronomy and Space Sciences, 2022 We derive weak turbulence and quasilinear models for relativistic charged particle dynamics in pitch-angle and energy space, due to interactions with electromagnetic waves propagating (anti-)parallel to a uniform background magnetic field.

Determining Pitch-Angle Diffusion Coefficients for Electrons in Whistler Turbulence
Physics, 2022 Transport of energetic electrons in the heliosphere is governed by resonant interaction with plasma waves, for electrons with sub-GeV kinetic energies specifically with dispersive modes in the whistler regime.

ON THE SPECTRUM OF ELECTROMAGNETIC WAVES IN ONE-DIMENSIONAL DEFECTIVE PHOTON CRYSTAL BORDERING ON CONDUCTING MEDIUM [PDF]
Радиофизика и электроника, 2016 Currently much attention is paid to investigation of electromagnetic properties of defective photon crystals. This is stipulated by both the occurrence of plasma and defective waves in such crystals and the zone nature of the waves spectrum.

Relativistic self focusing and frequency shift of super-Gaussian laser beam in plasma
Results in Physics, 2020 Relativistic self focusing and frequency shift of laser beam having super-Gaussian profile in space and Gaussian profile in time is studied in a plasma. The relativistic mass nonlinearity is found to cause time dependent self focusing of the laser pulse ...

Nonlinear plasma wave in magnetized plasmas [PDF]
Physics of Plasmas, 2013 Nonlinear axisymmetric cylindrical plasma oscillations in magnetized collisionless plasmas are a model for the electron fluid collapse on the axis behind an ultrashort relativisically intense laser pulse exciting a plasma wake wave. We present an analytical description of the strongly nonlinear oscillations showing that the magnetic field prevents ...

Space Weather, 2023 It is believed that galactic cosmic rays and solar energetic particles are the two major sources of ionizing radiation. However, the radiation source may also be due to relativistic electrons that are associated with precipitation from the Van Allen ...

Second-order perturbations in Alfvén waves in finite pressure plasma
Solar-Terrestrial Physics, 2022 It is shown first that in finite pressure plasma, just as in cold plasma, Alfvén waves created by an initial perturbation generate plasma flows and decreases in the magnetic field, which propagate along with these waves.
