Abstract
The maintenance of a microwave gas discharge of a standing surface electromagnetic wave (SEW) in the dipolar mode is studied. The standing wave was formed between two flat mirrors that create an open resonator type structure on the surface wave. The measured Q factor of the open resonator is several tens. The electric field structures of a free discharge and a discharge supported by a standing surface wave field are determined. It is shown that resonance on a purely surface wave is excited in this system. With an increase in the field energy between the mirrors by 8–10 dB, the concentration of electrons increases by about 50%. The ratios of the surface wave field energies in the plasma and in the space surrounding the discharge both in the case of a free discharge and during resonance are estimated. The results of experiments and numerical simulations show that the structure of the discharge depends on the excited mode of steady-state SEWs.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
