PROPAGATION OF LOW FREQUENCY ELECTROMAGNETIC WAVES IN THE EARTH IONOSPHERE WAVEGUIDE,
Abstract
The report gives a concise review of the present state of research on the propagation of very low frequency (VLF) and extremely low frequency (ELF) waves in the surface waveguide. Calculated values of refraction and damping coefficients, taking neutral particles into account, are given for both the lower ionosphere (D region), and the outer ionosphere, to heights of 3000 to 6000 km. Various theoretical formulas for the field in a waveguide, derived both rigorously and by asymptotic methods, are subjected to analysis, and the theoretical results are compared with most of the experimental data to be found in the literature. Almost all of the world's available information is used (255 names). The book has 54 illustrations and 13 tables.
