Electromagnetic radiation of simulated mid-gap streamers [PDF]

, 2016
Electromagnetic field from simulated double-headed mid-gap streamers is computed. The effect of the applied electric field is studied by considering electric fields higher than the conventional breakdown threshold (‘overvoltage’).

Stochastic Model of Breakdown Nucleation under Intense Electric Fields

, 2018
Plastic response due to dislocation activity under intense electric fields is proposed as a source of breakdown. A model is formulated based on stochastic multiplication and arrest under the stress generated by the field.
