Scattering of an Obliquely Incident Plane Electromagnetic Wave by a Magnetized Plasma Column: Energy Flow Patterns at Plasmon Resonances

Abstract

Abstract-The scattering of an obliquely incident H-polarized plane electromagnetic wave by a magnetized plasma column is studied. It is assumed that the column is located in free space and aligned with an external static magnetic field. The emphasis is placed on the case where the angular frequency of the incident wave coincides with one of the surface-or volume-plasmon resonance frequencies of the column. The spatial structures of the field and energy flow patterns in the near zone of the column are analyzed, and the location of the regions with a greatly enhanced magnitude of the timeaveraged Poynting vector is determined. It is shown that the sign reversal of the longitudinal energy-flow component that is parallel to the column axis can occur when passing across the boundary between the inner region of the column and the surrounding medium.

Electromagnetic resonance scattering by an array of magnetized plasma cylinders

“…Recall that in the case considered, a single cylinder has quasistatic multipole surface-plasmon resonances [7,8] at the frequencies which will be denoted as ω SP,m . At the same time, an equidistant infinite array of parallel cylinders for fixed angles θ and ψ has the so-called Rayleigh-Wood diffraction anomalies at the frequencies hereafter denoted as ω (±) n (n = 1, 2, .…”

Radiation From a Dipole Antenna Located Outside a Cylindrical Density Depletion in a Magnetoplasma Under Resonance Scattering Conditions

“…Moreover, additional resonance peaks can be observed near electron cyclotron harmonics in a warm bounded magnetoplasma due to the excitation of Buchsbaum-Hasegawa modes [31,32]. As a rule, the resonance scattering of the electromagnetic radiation incident from free space on a single axially magnetized plasma column or a set of such columns is characterized by many intriguing behaviors of not only the near-and far-zone fields but also the energy-flow field lines [33][34][35].…”
