Discovery of 1 Hz Range Modulation of Isolated Proton Aurora at Subauroral Latitudes

Geophysical Research Letters, 2018
Isolated proton aurora (IPA) is a manifestation of the wave‐particle interaction visible at subauroral latitudes, with activity on many timescales. We herein present the first observational evidence of rapid luminous modulation of IPA correlated with ...

Review of Controlled Excitation of Non-linear Wave-Particle Interactions in the Magnetosphere

Frontiers in Astronomy and Space Sciences, 2019
Controlled experiments involving injection of 0.5 Hz–8 kHz electromagnetic waves into the Earth's magnetosphere have played an important role in discovering and elucidating wave-particle interactions in near-Earth space.

Study on W-band sheet-beam traveling-wave tube based on flat-roofed sine waveguide

AIP Advances, 2018
A W-band sheet electron beam (SEB) traveling-wave tube (TWT) based on flat-roofed sine waveguide slow-wave structure (FRSWG-SWS) is proposed. The sine wave of the metal grating is replaced by a flat-roofed sine wave around the electron beam tunnel.

Detection of ultrafast electron energization by whistler-mode chorus waves in the magnetosphere of Earth

Scientific Reports
Electromagnetic whistler-mode chorus waves are a key driver of variations in energetic electron fluxes in the Earth’s magnetosphere through the wave-particle interaction.

Backward test particle simulation of nonlinear cyclotron wave-particle interactions in the radiation belts

Frontiers in Astronomy and Space Sciences
Wave-particle interaction plays a crucial role in the dynamics of the Earth’s radiation belts. Cyclotron resonance between coherent whistler mode electromagnetic waves and energetic electrons of the radiation belts is often called a coherent instability.

Autonomous quantum to classical transitions and the generalized imaging theorem

New Journal of Physics, 2016
The mechanism of the transition of a dynamical system from quantum to classical mechanics is of continuing interest. Practically it is of importance for the interpretation of multi-particle coincidence measurements performed at macroscopic distances from

Acoustically mediated long-range interaction among multiple spherical particles exposed to a plane standing wave

New Journal of Physics, 2016
In this work, we study the acoustically mediated interaction forces among multiple well-separated spherical particles trapped in the same node or antinode plane of a standing wave.

Significance of Wave-Particle Interaction Analyzer for direct measurements of nonlinear wave-particle interactions

Significance of Wave-Particle Interaction Analyzer for direct measurements of nonlinear wave-particle interactions
In the upcoming JAXA/ERG satellite mission, Wave Particle Interaction Analyzer (WPIA) will be installed as an onboard software function. We study the statistical significance of the WPIA for measurement of the energy transfer process between energetic electrons and whistler-mode chorus emissions in the Earth's inner magnetosphere.
