—Statistical characteristics of scattered electromagnetic waves by turbulent magnetized plasma slab with electron density and magnetic field fluctuations are considered via the perturbation method and boundary conditions. Magnetic field fluctuates both in magnitude and direction. Analytical expressions for the component of scattered electric field,… (More)

– The features of angle-of-arrival (AOA) of scattered radiation using the geometrical optics approximation and statistical simulation (Monte Carlo method) are studied in the paper. Analytical expressions are derived for the power law spectrum of electron density fluctuations and numerically calculated at different angles of inclination of geomagnetic field… (More)

—Features of spatial power spectrum (SPS) of scattered radiation in a randomly inhomogeneous medium with strongly prolated anisotropic inhomogeneities of dielectric permittivity are investigated. In single scattering approximation, it has been shown that a pronounced gap along a direction of prolate inhomogeneities appears in SPS. Features of SPS of… (More)

Using an analogy method the frequencies of new modes of the electromagnetic planetary-scale waves (with a wavelength of 10 3 km or more), having a weather forming nature, are found at different ionospheric altitudes. This method gives the possibility to determine spectra of iono-spheric electromagnetic perturbations directly from the dynamic equations… (More)

—Statistical characteristics of multiply scattered electromagnetic waves in turbulent magnetized plasma with both electron density and external magnetic field fluctuations are considered. Analytical expression for phase fluctuations of scattered radiation is derived using the smooth perturbation method. Correlation and wave structure functions of the phase… (More)

A problem of propagation of very long planetary waves in the upper atmosphere of the Earth is investigated. A new exact solution of the magnetohydrodynamics equations of the ionosphere in the spherical coordinate system is found taking into account the Earth's rotation and geomagnetic field. The general dispersion equation for the planetary waves in the E… (More)

Second order statistical moment of the ordinary and extraordinary waves scattered by turbulent magnetized plasma slab with electron density and magnetic field fluctuations is analytically calculated applying the perturbation method. Numerical calculations are carried out for the anisotropic Gaussian fluctuation spectrum at different anisotropy factor and… (More)
