Nonparallel Wave Propagation in an Asymmetric Magnetic Slab
The Astrophysical JournalTheoretical and numerical analyses of the behavior of magnetohydrodynamic (MHD) waves in solar atmospheric structures have a vital role in understanding the plasma dynamics of the Sun. Magneto-helioseismology is indebted to the insight gained from simple

MHD Modelling of Streamer waves
The research about the modelling of waves in the solar corona is conducted. In particular, global models for the solar corona, in which we model large-scale waves in coronal streamers, are constructed. These waves are excited by coronal mass ejections and allow to measure the magnetic field and speed of the solar wind with the aid of seismology.

Molecular Signatures of MHD Waves
Astrophysics and Space Science, 1995The small ion-neutral drift speeds attained in MHD waves lead to a significant increase in the rates of several important ion-molecule reactions. The effect on the deuterium chemistry of dark clouds could allow MHD wave motion to be observed directly. The results of some recent observations to test this theory are outlined.

Refraction and/or magnetic field curvature can lead to ‘geometrical mode coupling’ between the MHD modes. The effect is linear, but it is a finite‐wavelength effect. It is studied here for a simple configuration which is amenable to analysis and which illustrates the basic features of the coupling.

Plasma Physics and Controlled Fusion, 1986
Reviews recent developments in the theory of MHD waves in connection with radio-frequency heating in the Alfven wave and ion cyclotron ranges of frequencies (AWRF, ICRF). The account focuses on the discussion of full wave solutions and the oscillation spectra in bounded, generally inhomogeneous, plasmas. Original results are presented concerning forced

MHD Waves in Coronal Flux Tubes
Space Science Reviews, 1994The basic MHD waves of a coronal flux loop are investigated for the rectangular box model of a plasma with oblique magnetic field and line-tied at the ends. The waves found are completely different from those in a periodic box, representative for tokamaks.
