Abstract
The excitation of extremely low frequency (ELF) waves by a horizontal electric dipole in the earth-ionosphere waveguide can be obtained by a heuristic approach based upon the observation of a relationship between a horizontal electric dipole and a horizontal magnetic dipole. Then multiple imaging takes into account the effect of the ionosphere. This approximate derivation preserves the physical picture which is obscured by complex mathematics in rigorous analysis.
