Time dependent evolution of linear kinetic Alfv en waves in inhomogeneous plasma
نویسندگان
چکیده
The propagation of linear Kinetic Alfv en waves (KAWs) in inhomogeneous magnetized plasma has been studied while including inhomogeneities in transverse and parallel directions relative to the background magnetic field. The propagation of KAWs in inhomogeneous magnetized plasma is expected to play a key role in energy transfer and turbulence generation in space and laboratory plasmas. The inhomogeneity scale lengths in both directions may control the nature of fluctuations and localization of the waves. We present a theoretical study of the localization of KAWs, variations in magnetic field amplitude in time, and variation in the frequency spectra arising from inhomogeneities. The relevance of the model to space and laboratory observations is discussed. VC 2015 AIP Publishing LLC. [http://dx.doi.org/10.1063/1.4906882]

Temporal Evolution of Drift Alfv en Waves in an Inhomogeneous Plasma with Homogeneous Shear Flow
The temporal evolution of drift-Alfv en waves in a plasma ow with homogeneous shear is studied as an initial value problem without the use of spectral expansion in time. It is shown that the conventional modal structure of the drift-Alfv en instability (as well as drift and Alfv en waves) pertains only in the initial stage of its evolution. For larger times, non-modal e ects due to the velocity...
متن کاملLocalization of linear kinetic Alfv en wave in an inhomogeneous plasma and generation of turbulence
This paper presents a model for the propagation of Kinetic Alfv en waves (KAWs) in inhomogeneous plasma when the inhomogeneity is transverse to the background magnetic field. The semi-analytical technique and numerical simulations have been performed to study the KAW dynamics when plasma inhomogeneity is incorporated in the dynamics. The model equations are solved in order to study the localiza...
متن کاملAlfv En Wave Solitons and Solar Intermediate Drift Bursts
We investigate stationary solutions for Alfv en solitons propagating obliquely in a homogeneous magnetic eld. Due to their dispersive nature kinetic Alfv en waves can evolve into soliton like structures which propagate at velocities of the order of the Alfv en velocity in a direction inclined to the magnetic eld. In the rst model we keep the plasma < m e =m i. Kinetic Alfv en solitons in this c...
متن کاملLinear theory and measurements of electron oscillations in an inertial Alfv en wave
The physics of the aurora is one of the foremost unsolved problems of space physics. The mechanisms responsible for accelerating electrons that precipitate onto the ionosphere are not fully understood. For more than three decades, particle interactions with inertial Alfv en waves have been proposed as a possible means for accelerating electrons and generating auroras. Inertial Alfv en waves hav...
متن کاملElectrostatic broadband ELF wave
The linear and nonlinear kinetic properties of electrostatic oblique waves below the lower hybrid frequency are investigated. For propagation angles # = k k =k ? < q m e =m i the waves are damped by either parallel electron Landau or ion cyclotron damping. For T i =T e 1 the waves are only weakly damped and can propagate. These waves are called slow ion cyclotron (SIC) and slow ion acoustic (SI...
