Presents current research into electromagnetic computation theories with particular
emphasis on Finite-Difference Time-Domain Method This book is the first to consolidate …

Abstract Recently, Ala et al.(2008)[7] have proposed a soil ionization model, on the basis of
the dynamic soil-resistivity model of Liew and Darveniza (1974)[16], for finite-difference time …

In this paper, the simulation of towers cascade under lightning surge conditions is
presented. Finite-difference time-domain method is used to solve both the Maxwell's and …

A mathematical model for accurately computing, when combined with the Fast Fourier
Transform (FFT), the lightning currents flowing along a high voltage ac substation's …

Os desligamentos não programados que ocorrem em uma linha de transmissão constituem
um importante parâmetro na definição de seu desempenho, sendo a descarga atmosférica …

Neste trabalho é realizada uma avaliação da resposta impulsiva de aterramento com haste
concretada, considerando o efeito da ionização do solo. Para isso, o aterramento foi …
