Abstract

This paper presents a time-domain equivalent circuit approach for analyzing lightning-generated electromagnetic transients in modern buildings. The building is represented by a wire-plate structure and is modeled by the internal impedance and external inductance of current cells and the coefficients of potential cells. A vector-fitting technique is applied for modeling frequency-varying internal impedance for time-domain simulation. With this unique formulation, the number of unknown variables is reduced, and computational efficiency is improved significantly. Finally, lightning-generated impulse magnetic fields and voltages within a building are evaluated.
