Book Description
The subject of geomagnetic micropulsations has developed extremely rapidly and it is difficult to know when is an appropriate time to pause and assess the sum total of our knowledge-both observational and theoretical. There has in recent years been a tremendous increase in both the quantity and quality of data and also many theoretical ad vances in our understanding of the phenomenon. Undoubtedly there will be further progress in both areas but it seems worthwhile now to review both our knowledge and our ignorance. This book was essen tially completed by the end of April 1969 and tries to give a summary of the subject up to that time. The Earth is enclosed in the magnetosphere, a hollow carved out of the solar wind by the Earth's magnetic field. Above the ionosphere there is a very tenuous thermal plasma of partially ionized hydrogen in diffusive equilibrium with magnetic and gravitational forces, and ener getic protons and electrons that constitute the trapped Van Allen ra diation belts. Throughout this anisotropic and inhomogeneous plasma, natural and man-made electromagnetic energy propagates in a wide variety of modes and frequency bands. This book is concerned with that class of natural signals called geomagnetic micropulsations-short period (usually of the order of seconds or minutes) fluctuations of the Earth's magnetic field.

Book Description
The report reviews the fundamentals of high frequency geomagnetic micropulsations in the region of the electromagnetic spectrum from about 1-5 Hz. It then discusses, by reviewing the open literature, the large body of research performed in this discipline by Soviet scientists. Conclusions are not made as to whether or not the results of these investigations are, in fact, being applied towards functional communications systems. It is, however, demonstrated that the Soviet research is applicable and necessary to the possible future use of micropulsation modes for communications purposes. (Author).
