Propagation of electromagnetic field in an abnormal stratification of the upper ionosphere

摘要

The study of the propagation of electromagnetic field for an atmospheric surface duct require that the distance between receiving and transmitting end is arbitrarily chosen. So, we have evaluated the application of two integral transforms to the wave equation of Fitzgerald vector––a Laplace transform in time and a two-dimensional Fourier transform in the horizontal coordinates in space, which leads to an integral representation of the solution of the wave equation in the transform space. This integral representation determines the electromagnetic field in the ionosphere, which consists of a reflected wave that is superimposed upon the given incident wave.
