[en] Interaction of obliquely incident linearly polarized plane electromagnetic waves with a radially inhomogeneous plasma column of infinite length moving uniformly in the axial direction is treated analytically. It is found that the cross-polarized field components disappear at the incident angle Phi0=sin-1(v/sub z//c) (v/sub z/ is the velocity of the moving plasma column and c is the free-space velocity of light) for the case of an inhomogeneous plasma column with an arbitrary electron density profile. Numerical results for the differential scattering cross sections are obtained for a range of plasma velocities by using the two-point boundary-value method

[en] Closed-form solution for transient reflection from an isotropic cold lossy plasma half-space for TM-type polarization is obtained in the form of an infinite power series of a modified Bessel function of the first kind. The delta, unit step, and rectangular pulse excitations were considered. The obtained results are valid for an arbitrary value of the lossy parameter α/sub ν/=ν/ω/sub p/>0. Numerical results are presented to illustrate the effects of the incident angle and lossy parameter on the reflected waveform. Early time response at the incident angle theta/sub i/=π/4 is related to the time-domain Brewster angle

[en] The rate of the ion pair production, due to the beta and gamma radiation from the radioactive cloud, is presented in the analitical form. This model is applicable for the altitudes up to 150 km above the earth surface. The space - time variation of the electron and ion densities in the atmosphere have been determined by the use of a coupled set of the equations of continuity. The influence of these variations on the electromagnetic wave (EMW) propagation in the atmosphere has been studied. (author)

[en] The dispersion relations for the new waves excited by a suddenly created Lorentz media are derived and presented by the use of a Brillouin-like diagram. The amplitude and power transmission and reflection coefficients for these new modes are derived and discussed. It is shown that less than 4% of the pump wave power is transferred to the reflected modes
