Influence of the magnetic field diffusion on the magnetoacoustic wave coupling in a viscous plasma

We study the influence of the magnetic field diffusion on the magnetoacoustic wave coupling in a viscous plasma with a finite conductivity, situated in a strong inhomogeneous magnetic field. The plasma density and the intensity of the magnetic field are only functions of coordinate z. At the same time we studied the wave propagation along the Oz axis. A comparative study on the coupling of the magnetoacoustic waves propagating in the F2 ionospheric layer under the condition of finite and infinite conductivity respectively is made. (Author)
