Scattering of electromagnetic waves from an inhomogeneous magnetoplasma column moving in the axial direction

The problem of the scattering of an obliquely incident plane electromagnetic wave by a radially inhomogeneous magnetoplasma column of infinite length moving uniformly in the axial direction is discussed with the aid of the polarization current model based upon the Minkowski formulation in which a plasma medium is treated as a dispersive dielectric. For the analysis of the problem, a radially inhomogeneous plasma column is subdivided into a number of thin homogeneous coaxial layers, and the easier problem of the scattering by the stratified plasma column is solved instead of directly treating the wave equations for an inhomogeneous plasma column. For parabolic electron density profiles, the scattering properties of the moving inhomogeneous magnetoplasma column are investigated quantitatively with the aid of numerical examples.
