Description
Summary:Electric field excitation by a horizontal flooded source placed at the interface between two media has been considered. A solution to the problem has been represented in the form of integrals that contain a quickly oscillating Bessel function. Under the quasi-static approximation, general functions that describe a field in water have been represented using the Watson integrals through the well-studied modified Bessel functions. It has been shown that, in the region at a distance more than a skin-layer from the antenna, the vertical component is determined by the field that propagates exclusively in the lower medium, and components perpendicular to the antenna have the form of the waves that propagate in the upper medium without absorption and then penetrate deeply, changing by the exponential law.
