Abstract :
This paper is analyzed the attenuation rate of extremely low frequency (ELF) electromagnetic waves propagating in the Earth-ionosphere system, using the geodesic FDTD model. In the simulation both the classical two-exponential model and the “Knee” model of ionosphere are used. The resulting difference among using different algorithm are also explained.
