ɍȾɄ 533.951 ELECTROMAGNETIC WAVE DIFFRACTION BY METAL CYLINDER COATED WITH INHOMOGENEOUS MAGNETOACTIVE PLASMA SHEATH

Abstract

In our paper the task of diffraction of low frequency electromagnetic waves incident from a homogeneous magnetoactive plasma by a metal circular cylinder surrounded by radially inhomogeneous plasma sheath have been studied. The constant external magnetic field is parallel to a cylinder axis; the wavevector of incident plane wave is perpendicular to this axis. Plasma is cold and perturbations in it are governed by two-liquid hydrodynamic equations and Maxwell equations. On the basic of the exact solutions for fields in plasma sheath with linear profile of inhomogeneity the cross-section are obtained. The angular distribution of cross-sections is derived for various values of incident wavelength. It is shown that it is possible to control effectively this angular distributing by the change of wave frequency and strength and direction of the constant external magnetic field
