On the use of magnetic current loop source model in lightning electromagnetics

The paper deals with the use of antenna theory and the concept of magnetic current loop (MCL) source in lightning electromagnetics. The applications are related to lightning channel modeling and transient analysis of grounding system. The formulation is based on the corresponding Pocklington integro-differential equation, while the numerical solution is carried out by means of the Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM).
