On the Conductivity of a Magnetoactive Turbulent Plasma
The problem of determining the effective conductivity tensor of a
magnetoactive turbulent plasma is considered in the approximation of isolated
particles. Additional gyrotropicterms are shown to appear in the conductivity
tensor in the presence of mean, nonzero magnetic helicity. The dispersion of
propagating electro- magnetic waves changes, additional modes and additional
rotation of the polarization plane appear, and the waves can be amplified. The
properties acquired by plasma with helicity are similar those observed in
chiral and bianisotropic electrodynamic media.Comment: 15 page
New branches of natural ultra low-frequency electromagnetic oscillations of the ionospheric resonator
Planetary waves and vortex structures in the ionosphere
The problem of propagation of large-scale vortices in the ionosphere is
investigated. Permanently acting fundamental factors have been discovered
making it possible to reveal the mechanisms of generation of large-scale
vortices and planetary waves in conductive atmosphere
