Electromagnetic wave scattering by an array of axially magnetized parallel plasma columns

Abstract

We study scattering of an electromagnetic H-polarized plane wave by an equidistant array of axially magnetized plasma columns located perpendicular to the incidence plane in free space. Conditions are determined under which the individual and collective resonant effects in the considered system lead to the formation of an electromagnetic field with a 2D-periodic structure of chessboard type near the array. The array parameters are found for which a giant enhancement of the scattered field takes place such that the field possesses a quasi-1D layered structure with alternating sharp maxima and deep minima.
