Abstract :
The geodesic FDTD method is applied to simulate surface responses caused by extremely low frequency (ELF) electromagnetic (EM) wave propagation for potential underground (UG) resource detection applications. The simulation space extends from 100km above the Earth´s surface to 100km below it. Object with specific dielectric values are buried to simulate possible UG resource. A model is establish for possible UG resource detection using ELF waves. Using these settings, surface responses are simulated and analyzed. Finally, potential application of inverse study using the simulation results are discussed.
