Modeling electromagnetic propagation in the Earth-ionosphere waveguide.

Modeling electromagnetic propagation in the Earth-ionosphere waveguide.

The ionosphere plays a role in radio propagation that varies strongly with frequency. At extremely low frequency (ELF: 3-3000 Hz) and very low frequency (VLF: 3-30 kHz), the ground and the ionosphere are good electrical conductors and form a spherical Earth-ionosphere waveguide. Many giants of the e...
