Generation of a Steady-State Overdense Plasma by Microwaves near the Dipole Resonance of a Coaxial Discharge Device

Abstract

At electron densities above the dipole resonance of a coaxial plasma-waveguide-system a steadystate discharge has been generated. The measured complex wave vector is compared to the calculated electromagnetic dispersion relation and allows conclusions concerning electron densities as well as relative electron density profiles. Attention is paid to the occurrence of parametric decay
