Propagation of Electromagnetic Waves in the Earth Crust Waveguide from ELF to VLF
Abstract
Using an idealized model, the attenuation rate of the lowest order mode is calculated for a range of deep crustal conductivities. It is shown that attenuation rates may be as low as 1 dB/100 km at 1 Hz for a waveguide conductivity less than 0.000001 mhos/m. Numerical values of the propagation parameters are appended.
