“…Despite the constantly ongoing progress in the development and application of numerical methods in electromagnetics it turns out that the computation of lightning-related effects in the framework of Electromagnetic Compatibility (EMC) still constitutes a highly challenging task. This is due to a number of difficulties that can be characterized as follows (Apra et al, 2008;Anatzki and Gronwald, 2012;Prost et al, 2013): First, the modeling of an actual lightning channel as electromagnetic source requires to turn a physically complicated and geometrically extended excitation into a numerical model. Second, the rather long duration of a lightning electromagnetic pulse (LEMP), together with its associated low-frequency spectrum, requires both in time and frequency domain stable and efficient numerical algorithms.…”

Abstract. A formalism for the computation of lightning transfer functions by the method of moments, which involves shielding structures that may consist of layered, anisotropically conducting composite materials, is presented in this contribution. The composite materials, being of a type that is widely used in space- and aircraft design, are electrically characterized by an equivalent conductivity. As basis for the quantitative analysis the method of moments is used where shielding surfaces can be treated by a thin layer technique which utilizes analytical solutions inside the layer. Also the effect of an extended lightning channel can be taken into account. The method is applied to geometries that resemble an actual airplane fuselage.

“…The aims of these researchers are to evaluate, estimate, and analyze various lightning properties and their effects for different applications. Simulation models were developed to cater for all aspects of lightning such as lightning leader and its pattern [1][2][3], lightning electromagnetic field propagation [1,4,5], lightning induced voltage and current patterns on man-made systems [6][7][8][9], and lightning detection and localization using various sensing techniques [1]. However, most of the published works on lightning related simulation models have their own shortcomings.…”

“…Simulations of lightning effects on man-made systems were also carried out by Kato et al [12] and Baba and Rakov [5]. Several specific simulation approaches were developed to evaluate the effect of induced current on fast moving object like aircrafts [8,13], or to estimate inrush currents in power distribution transformers [9]. Some other researchers evaluate the lightning effects on power transmission lines [14] by considering at least two lightning aspects.…”

Various methods are used to locate cloud-to-ground lightning flashes. Even though a higher cost is incurred, a network of sensor stations is preferable to a single station due to the improved accuracy. For a single station measuring system, the accuracy of its analyses is mostly based on the chosen mathematical equations which can be solved in either linear or nonlinear mode. The sensitivity of the measuring equipment used is also particularly significant. This paper concentrates on the modelling of time of arrival (TOA) technique for locating a lightning flash by utilizing three broadband antennas. Consequently, by employing the developed model, the influences of geometric parameters on the accuracy of the model are evaluated. Therefore, a Matlab based simulation of the measuring system is developed. In the developed codes, randomly located lightning flash with its corresponding electromagnetic radiation was modelled. Results show that parameters such as lightning path shape, distance of the leader, and leader location can directly affect the accuracy of the TOA technique for extracting the azimuth and elevation.

“…However, they involve heavy tools which are not optimized for quick parameters optimization or measurement analysis, as they require lengthy computations, even with using a powerful parallel computer. On the other hand, much lighter models such as "stick models" have gained a lot of interest [2]. Based on the PEEC (Partial Element Equivalent Circuit) method, they have shown to be faster and sufficiently accurate in some aeronautical applications.…”
