Cross polarization of EM waves scattered by an isotropic inhomogeneous moving plasma column

摘要

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 Fgr;0=sin−1(vz/c) (vzis the velocity of the moving plasma column andcis 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.
