Reflection of resonance cone and plasma-filled waveguide modes
Abstract
The resonance cone excited by a radio-frequency antenna in a magnetoplasma is investigated in a large metallic plasma chamber. The large number of reflections of the resonance cone is found to be the explanation for the extensively observed and studied ''Trivelpiece-Gould'' modes for a plasma-filled waveguide. A dispersion relation is found, in close agreement with previous studies, which describes accurately the experimentally observed wavelike structures.
