Modeling of a New Electron Acceleration Mechanism Ahead of Streamers
Ihaddadene, Kevin M. A.; Dwyer, Joseph R.; Liu, Ningyu; Celestin, Sebastien; Shi, Feng (2020-05-26)
Head‐on collisions between negative and positive streamers have been proposed as a mechanism behind X‐ray emissions by laboratory spark discharges. Recent simulations using plasma fluid and particle in cell models of a ...
VHF and UHF Electromagnetic Radiation Produced by Streamers in Lightning
Shi, Feng; Dwyer, Joseph R.; Ihaddadene, Kevin M.A.; Liu, Ningyu; https://orcid.org/0000-0003-3406-9383 (2020-03-10)
In this letter, we report simulation results of streamer propagation and collision that produce electromagnetic radiation in the very high frequency (VHF) and ultra high frequency (UHF) bands. The streamers are initiated ...
