Scattering properties of a finite array of magnetized plasma cylinders at the surface plasmon resonances

Abstract

The scattering properties of a finite array of magnetized plasma cylinders are studied theoretically by using the multiple scattering approach. It is assumed that the array, whose elements are aligned with an external static magnetic field and located equidistantly in free space, is illuminated by an obliquely incident H-polarized plane electromagnetic wave. The far-zone scattering patterns for the array consisting of a relatively large but finite number of cylinders are analyzed in the case where the individual and collective mechanisms of resonance scattering are pronounced in such a system. Numerical calculations performed in the radio-frequency range demonstrate promising prospects for controlling the scattering characteristics of plasma-based arrays near the frequencies of plasmon resonances of their cylindrical elements.
