Physics of Plasmas, Volume 30, Issue 4, April 2023. We investigate the impact of relativistic effects on upper hybrid (UH) waves in plasmas with thermal electrons, particularly focusing on modifications of the conditions under which UH wave trapping an…
Physics of Plasmas, Volume 30, Issue 4, April 2023. Retarding field energy analyzers and Langmuir probes are routinely used to obtain ion and electron-energy distribution functions (IEDF and EEDF). These typically require knowledge of the first and sec…
Physics of Plasmas, Volume 30, Issue 4, April 2023. Above the sunlit surface of Mercury, the properties and formation of dusty plasmas are investigated. It is demonstrated that the dusty plasmas are formed for subsolar angles exceeding approximately 76…
Physics of Plasmas, Volume 30, Issue 4, April 2023. Transverse depinning dynamics of a periodic-square-substrate modulated two-dimensional dusty plasma solid driven by a constant force in the longitudinal direction are investigated using Langevin dynam…
Physics of Plasmas, Volume 30, Issue 4, April 2023. In this paper, the effects of pulse voltage rise time on the nanosecond pulsed breakdown of the nitrogen spark switch at atmospheric pressure are analyzed. Based on the assumption of initial electrons…
Physics of Plasmas, Volume 30, Issue 4, April 2023. The effects of pulse rise time on the temporal evolution of electron energy and density under repetitive nanosecond pulses in atmospheric nitrogen with 100 ppm oxygen impurities are investigated in th…
Physics of Plasmas, Volume 30, Issue 4, April 2023. The results of the investigation of the breakdown characteristics of the planar “open” discharge and open discharge with the generation of counter-propagating electron beams under excitation by pulses…
Physics of Plasmas, Volume 30, Issue 4, April 2023. In recent years, the interaction of electromagnetic waves (EM) with plasma sources under argon and helium discharges has been extensively studied due to its potential applications in plasma stealth. H…
Physics of Plasmas, Volume 30, Issue 4, April 2023. Cylindrical Langmuir probe measurements in a low-pressure DC argon discharge are used to obtain the spatial evolution of ion, cold and hot electron parameters across the cathodic pre-sheath. The catho…
Physics of Plasmas, Volume 30, Issue 4, April 2023. In sub-THz communication systems, compact, high-power, tunable radiation sources are required. Backward wave oscillators (BWO) have been practical devices for THz communication, but the maximum output…
