Abstract
The general historical and methodological aspects in the theory of waves guided by earth surface are analyzed. The local approximation of convex spherical earth surface by a flat surface is shown to be inefficient (according to the electrodynamics viewpoint). The boundaryvalue problem of “pseudo surface” waves of an open spherical waveguide is posed and solved. The peak amplitude of the field and corresponding components of the Poynting vector for the waves is demonstrated to be not appressed to earth surface; this fundamentally differs from the theory of surface waves. Accordingly, solving the practical problem of wave excitation by means of surface antennas seems to have little effect. Therefore, to design coast-earth radio tracking systems for observing sea surface beyond the horizontal line, it is suggested to employ the following fact. The field of these waves in the underwater (underground) area is always appressed to the concave spherical surface.
