Planning for Observations of the Plasma Waves by Sounding Rockets in Antarctica

Antarctic Record, 1975
The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of the ...

ULF waves with drift resonance and drift-bounce resonance energy sources as observed in artificially-induced HF radar backscatter [PDF]

Annales Geophysicae, 2001
HF radar backscatter which has been artificially-induced by a high power RF facility such as the EISCAT heater at Tromsø has been demonstrated to provide ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

DNS of the interaction between a shock wave and a turbulent shear flow: some effects of anisotropy [PDF]

, 2007
Direct numerical simulation is used to study the interaction of a Mach 1.5 shock wave and various types of anisotropic turbulent flows. We compare the interaction of isotropic, axisymmetric and sheared turbulences (sometimes combined), with a specific ...

Data processing in Software-type Wave–Particle Interaction Analyzer onboard the Arase satellite

Earth, Planets and Space, 2018
The software-type wave–particle interaction analyzer (S-WPIA) is an instrument package onboard the Arase satellite, which studies the magnetosphere. The S-WPIA represents a new method for directly observing wave–particle interactions onboard a spacecraft

Nonlinear wave growth theory of whistler-mode chorus and hiss emissions in the magnetosphere

Earth, Planets and Space, 2021
Nonlinear processes associated with the generation process of whistler-mode chorus emissions are summarized. The nonlinear dynamics of energetic electrons interacting with a coherent whistler-mode wave and the formation of electromagnetic electron holes ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Time simulation of the nonlinear wave–particle interaction in meters-long traveling-wave tubes

, 2021
International audienceWe propose a multi-particle self-consistent Hamiltonian (derived from an N-body description) that is applicable for periodic structures such as traveling-wave tubes (TWTs), gyrotrons, free-electron lasers, or particle accelerators ...

Interaction of Submerged Breakwater by a Solitary Wave Using WC-SPH Method

Modelling and Simulation in Engineering, 2014
Interaction of a solitary wave and submerged breakwater is studied in a meshless, Lagrangian approach. For this purpose, a two-dimensional smoothed particle hydrodynamics (SPH) code is developed. Furthermore, an extensive set of simulations is conducted.

On the nature of particle energization via resonant wave-particle interaction in the inhomogeneous magnetospheric plasma [PDF]

Annales Geophysicae, 2011
When a quasi-monochromatic wave propagating in an inhomogeneous magnetoplasma has sufficiently large amplitude, there exist phase-trapped resonant particles whose energy increases or decreases depending on the "sign" of inhomogeneity.
