Channel modeling for through-the-earth (TTE) communication systems

This dissertation presents channel modeling in TTE communication environments from wellestablished analytic models, measurements and electromagnetic simulations. For those scenarios, the main original contribution are the statistical results for the effective electric conductivity as well as the attenuation experimented by magnetic field while propagating Through-The-Earth. The simulation results present here, in addition to confirming the behavior of empirical models, extrapolate to frequencies not studied via statistical tools.
