Dipole Resonant Modes of an Ionized Gas Column

Abstract

It is shown by a quasi-static treatment there is not one but a multiplicity of plasma resonant modes which will emit dipole radiation in a cylindrical column of ionized gas with a radially symmetrical but non-uniform electron density. It is shown that the multiple resonances obtained by Romell in scattering of short waves from a gas discharge column may be qualitatively explained assuming a reasonable electron distribution.
