A theory is given of the spectral distribution and the absolute amount of low frequency electromagnetic radiation emitted from a vertical lightning stroke from cloud to ground. The calculation depends on an assumed physical mechanism for the flow of charge on the discharge channel, but the model cor
## Abstract This paper studies the scattering of electromagnetic waves from a (local) perturbation of a fixed surface, the boundary of a given obstacle in โ^3^. The goal is to produce an algorithm for solving boundary value problems in the exterior of the perturbed domain solely based on the knowle
in which Q is the charge density, connected with the current density by the equation of continuity c -1 div i -----ik~. (2) As is well known, eqs (1) admit one and only one solution that is compatible with Sommerfeld's radiation condition at infinity. This unique solution is conveniently expressed
