Abstract

Analysis of lightning electromagnetic field using the finite-difference time-domain (FDTD) method have been studied in recent year However, large-scale analysis on real environment have not been considered, because the FDTD method requires huge computational cost on large-scale analysis. We proposed a three-dimensional moving window FDTD (MW-FDTD) with parallel computation and applied to large-scale analysis of lightning electromagnetic field with a real numerical terrain model. In this paper, we have studied about large-scale analysis of lightning electromagnetic field with real urban models considering many buildings using our MW-FDTD with parallel computation. We have shown effects of observed electromagnetic field on urban model.
