Hydromagnetic wave in an inhomogeneous cylindrical plasma

On electromagnetic wave momentum transfer to an inhomogeneous plasma

2014 Electromagnetic plane wave momentum transfer to an inhomogeneous plasma slab has been evaluated for an arbitrary reflecting and absorbing plasma density profile based on Euler’s equation of motion but including a ponderomotive term. In the limit where the plasma density follows a step function, the Fresnel formulae for the coefficient of reflectivity have been obtained for both normal and ...

Wave Propagation in an Inhomogeneous Medium

Localization 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...

Self oscillations of a forced inhomogeneous hydromagnetic cavity

We study the nonlinear development of MHD waves in a one dimensional cavity stratified by gravity and embedded in background, homogeneous, vertical magnetic field which produces an anisotropic viscosity. The plasma is compressible and its temperature is homogeneous over most of the cavity, rising to large values in a narrow ‘transition zone’ near its upper boundary. Disturbances at the cavity’s...

On the dispersion relation for the kinetic Alfvén wave in an inhomogeneous plasma

The kinetic Alfvén wave has been recognized as an important wave mode in magnetospheric plasmas and laboratory plasmas, and has potential application in many areas of cosmic plasma physics. The kinetic dispersion relation of this mode has been described including finite frequency and finite ion gyroradius corrections. Laboratory plasmas as well as plasmas in space often contain strong gradients...
