摘要

The features of electromagnetic wave scattering from cylindrical objects have received much careful study in view of their wide use in various electrodynamic systems. In the radio-frequency range, magnetized plasma scatterers of cylindrical shape have recently attracted enhanced attention as tunable resonant elements of antenna arrays with controllable properties [1]. Despite significant progress in the theory of resonance scattering of electromagnetic waves from plasma objects, some important effects occurring due to competition of radiative and dissipative energy loss in such scattereres are yet to be analyzed in greater detail. Recall that energy dissipation in a cold plasma is related to collisions of charged particles in it. It is the purpose of this work to discuss some unexpected features of scattering of electromagnetic waves by a magnetized plasma cylinder at the frequencies of plasmon resonances with allowance for collisions of charged particles in the plasma.
