Kukushkin A. V., Zotov A. V. Radio-surveillance systems based on pseudo-surface electromagnetic waves on the spherical surface of the earth (sea)


General analysis of history and methodology of theory for wave propagation on the Earth surface is presented. Inconsistency, from the point of view of electrodynamics, of a local approximation of the spherical earth as a plane is shown. A boundary-value problem for an open spherical waveguide pseudo-surface waves is formulated and solved. These waves’ field amplitude maximum and the corresponding Poynting vector components maximums are shown to be directed away from the Earth surface rather than towards it as is necessary for the surface wave theory. In this connection, it is noted that the generation of such waves by land-based antennas seems impractical; and it is suggested that the fact that the underground or underwater part of fields of such waves, quite the opposite, is always directed towards the concave spherical surface, should be used for creation of shore-based radio-surveillance systems for monitoring the sea surface beyond the horizon.

Keywords: radio-surveillance systems, an open spherical waveguide, surface waves, leaky waves, pseudo-surface wave, Zenneck wave, Sommerfeld wave.
