'Geoelectromagnetic Waves', a term coined for the first time in this book, examines waves of natural origin (both terrestrial and extra-terrestrial) which disturb the electromagnetic field of the Earth.
The Earth's crust and ocean, atmosphere and ionosphere, magnetosphere and interplanetary medium are filled with waves of various lengths and frequencies and the study and observation of these waves allows us to better understand the world in which we live, thus providing the basis for useful practical applications. This book provides a comprehensive and unifying treatment of the origin and application of geoelectromagnetic waves. Throughout the work the authors demonstrate a physical understanding of the phenomena with theoretical results compared against ground and satellite based data. In this way a practical picture is built up of the effects of geomagnetic pulsations.
