Abstract

The spatial stability is analyzed for the geodesic finite-difference time domain (FDTD) method. The analysis is based on the finite integration technique (FIT) and tensor analysis. After rigorous theoretical analysis, we point out that the present geodesic FDTD method can provide approximate but long-time stable solutions to the extremely low-frequency (ELF) electromagnetic wave propagation problems in the Earth-ionosphere system. We have also simulated an example of longtime wave propagation to prove our analysis.
