EM scattering from a vertical column of ionization in the earth-ionosphere waveguide
Abstract
An idealized analysis is given for the mode conversion in the earth-ionosphere waveguide produced by a tongue or stalactite of ionization below the normal reflecting layer. It is shown that the scattered signal may be significant even for perturbations located off the great circle path between source and observer.
