Lightning induced disturbances in buried cables - Part I: Theory

Farhad Rachidi-Haeri, Emanuel Petrache, Mario Paolone

In this paper, we present a review of theoretical methods to compute lightning induced currents and voltages on buried cables. The evaluation of such induced disturbances requires the calculation of the electric field produced by lightning along the cable ...

Inclusion of an automatic adaptive sampling method in NEC

Farhad Rachidi-Haeri, Abraham Rubinstein

As sampling is taking place, the most active regions of the spectrum can be identified (i.e. the vicinity of spectral peaks). By selectively increasing the spectral density within those regions improves the quality of the total spectral representation redu ...

Lightning strikes to elevated structures: influence grounding conditions on currents and electromagnetic fields

Farhad Rachidi-Haeri, Marcos Rubinstein, Emanuel Petrache, Davide Pavanello

This paper presents an analysis of lightning return strokes to tall structures. The interaction of lightning with a tall structure is modeled using the antenna theory. The finite ground conductivity as well as the buried grounding system of the tall struct ...

Far-field-current relationship based on the TL model for lightning return strokes to elevated strike objects

Farhad Rachidi-Haeri, Marcos Rubinstein, José-Luis Bermudez, Davide Pavanello, Mario Paolone

New general expressions relating lightning return stroke currents and far radiated electric and magnetic fields are proposed, taking into account the effect of an elevated strike object, whose presence is included as an extension to the transmission line ( ...

On wire-grid representation of solid metallic surfaces

Farhad Rachidi-Haeri, Marcos Rubinstein, Abraham Rubinstein

This paper deals with the wire-grid representation of metallic surfaces in numerical electromagnetic modeling. We discuss in particular the adequacy of the well known and widely used equal area rule (EAR) to calculate the radii of wire-grid models. We show ...
