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.

Unsteadiness in shock-wave/boundary layer interactions

, 2010
The need for better understanding of the low-frequency unsteadiness observed in shockwave/turbulent boundary layer interactions has been driving research in this area forseveral decades.

Gravity optimised particle filter for hand tracking [PDF]

, 2014
This paper presents a gravity optimised particle filter (GOPF) where the magnitude of the gravitational force for every particle is proportional to its weight. GOPF attracts nearby particles and replicates new particles as if moving the particles towards

Bosonic spectral function and the electron-phonon interaction in HTSC cuprates [PDF]

, 2010
In this paper we discuss experimental evidence related to the structure and origin of the bosonic spectral function alpha 2F (omega) in high-temperature superconducting (HTSC) cuprates at and near optimal doping.

Identify the nonlinear wave‐particle interaction regime in rising tone chorus generation [PDF]

, 2017
Nonlinear wave-particle interaction during chorus wave generation was assumed to be in the adiabatic regime in previous studies, i.e., the particle phase-space trapping timescale (τtr) is considered to be much smaller than the nonlinear dynamics ...

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.

Vortex/inflectional-wave interactions with weakly three-dimensional input

, 1997
The subtle impact of the spanwise scaling in nonlinear interactions between oblique instability waves and the induced longitudinal vortex field is considered theoretically for the case of a Rayleigh-unstable boundary-layer flow, at large Reynolds numbers.
