THEORY OF PROPAGATION OF VERY LONG WAVES
Abstract
An attempt is made to match experimental and theoretical data on long-distance propagation of superlong (wave-lengths of several times ten kilometers) waves around the earth. Since there is no probability distribution function for the experimental data, the matching is carried out approximately by the method of mixed initial data, where all the data on the field and on the medium are divided into two groups - reliable and unreliable. Several models are proposed for the propagation along the earth's surface and in the ionosphere with an attempt to include all the geophysical factors which influence the far field of superlong radio waves. Only the waveguide channel adjacent to the earth is considered. The method of normal waves which can be used to solve waveguide propagation problems for sound waves in the ocean, infrasound waves in the atmosphere, seismic waves in the earth, etc., is also developed.
