TL;DR: In this paper, a nonlinear resistive element model was proposed to model the current wave propagation along the lightning return-stroke channel (RSC), where resistive elements were considered as nonlinear distributed load whose resistance is a function of both current and time.

TL;DR: In this article, a theoretical method is presented to study the effects of tall buildings on the measurement of lightning electromagnetic fields, and it is shown that the perturbed electromagnetic fields due to the presence of the metallic structure of a building can be determined using an electric field integral equation in time domain.

TL;DR: In this article, the transient response of a thin wire in the presence of a half-space is calculated with a new formulation of the Method of Moments (MoM) in time domain, based on a novel Time-Domain Mixed Potential Integral Equation (TD-MPIE), using complex-time Green's functions.

TL;DR: In this article, the use of an open-ended waveguide probe for detection and sizing of fatigue cracks in metals is explained and the signals associated with elliptical cracks are examined and techniques for inverting crack signals to crack dimensions are outlined.

TL;DR: In this paper, the authors present a semianalytical method for calculating the electromagnetic field distribution in a multilayer slab conductor, which is a very advanced and comprehensive method because there is no limitation for the shape of the exciter and the number of layers.
