Application of Genetic Algorithm to Estimation of Function Parameters in Lightning Currents Approximations

International Journal of Antennas and Propagation, 2017
Genetic algorithm (GA) is applied for the estimation of two-peaked analytically extended function (2P-AEF) parameters in this paper. 2P-AEF is used for approximation of measured and typical lightning discharge currents.

Lightning for Energy and Material Uses: A Structured Review

Global Challenges, 2020
The average atmospheric charge density of Earth is neutral. Charge built up from thunderstorms and lightning phenomena is offset by oceanic surface charging, and offers a source of energy that has not been harnessed broadly.

Wave Profile for Current Bearing Antiforce Waves [PDF]

, 2013
For fluid dynamical analysis of breakdown waves, we employ a one-dimensional, three-component (electrons, ions and neutral particles) fluid model to describe a steady-state, ionizing wave propagating counter to strong electric fields.
