This book was released on 2018-07-08 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The West Virginia State College Community College Division NASA Magnetic Earth Ionosphere Resonant Frequencies (MEIRF) study is described. During this contract period, the two most significant and professionally rewarding events were the presentation of the research activity at the Sir Isaac Newton Conference in St. Petersburg, Russia, and the second Day of Discovery Conference, focusing on economic recovery in West Virginia. An active antenna concept utilizing a signal feedback principle similar to regenerative receivers used in early radio was studied. The device has potential for ELF research and other commercial applications for improved signal reception. Finally, work continues to progress on the development of a prototype monitoring station. Signal monitoring, data display, and data storage are major areas of activity. In addition, we plan to continue our dissemination of research activity through presentations at seminars and other universities. Spaniol, Craig Unspecified Center...

Download or read book Resonances in the Earth Ionosphere Cavity written by A.P. Nickolaenko and published by Springer Science & Business Media. This book was released on 2002-07-31 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on electromagnetic resonance phenomena describes a general approach to physical problems, ways to solve them, and properties of the solutions obtained. Attention is given to the discussion and interpretation of formal and experimental data and their links to global atmospheric conditions such as the dynamics of global thunderstorm activity, variations of the effective height of the lower ionosphere, etc. Schumann resonance is related to worldwide thunderstorm activity, and simultaneously, to global properties of the lower ionosphere. Transverse resonance is predominantly a local phenomenon containing information on the local height and conductivity of the lower ionosphere and on nearby thunderstorm activity. Transient events in ELF-VLF radio propagation are also treated. These are natural pulsed radio signals and/or abrupt changes of manmade VLF radio signals. The transients associated with cloud-to-ionosphere discharges (red sprites, blue jets, trolls) are discussed, and clarification of the underlying physical ideas and their practical applications to pioneer results achieved in the field recently are emphasised.

Download or read book Schumann Resonance for Tyros written by Alexander Nickolaenko and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schumann resonance has been studied for more than half a century. The field became popular among researchers of the terrestrial environment using natural sources of electromagnetic radiation—lightning strokes, primarily—and now many Schumann observatories have been established around the world. A huge number of publications can be found in the literature, the most recent collection of which was presented in a special Schumann resonance section of the journal Radio Science in 2007. The massive publications, however, impede finding information about how to organize measurements and start observations of global electromagnetic resonance. Relevant information is scattered throughout many publications, which are not always available. The goal of this book is to collect all necessary data in a single edition in order to describe the demands of the necessary equipment and the field-site as well as the impact of industrial and natural interference, and to demonstrate typical results and obstacles often met in measurements. The authors not only provide representative results but also describe unusual radio signals in the extremely low-frequency (ELF) band and discuss signals in the adjacent frequency ranges.

Download or read book Geoelectromagnetic Waves written by Anatol V. Guglielmi and published by CRC Press. This book was released on 1996 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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.

This book was released on 2008-01-15 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is a fascinating text that integrates topics pertaining to all scales of the MHD-waves, emphasizing the linkages between the ULF-waves below the ionosphere on the ground and magnetospheric MHD-waves. It will be most helpful to graduate and post-graduate students, familiar with advanced calculus, who study the science of MHD-waves in the magnetosphere and ionosphere. The book deals with Ultra-Low-Frequency (ULF)-electromagnetic waves observed on the Earth and in Space.

Available in PDF, EPUB and Kindle. Book excerpt: The fourth edition of Physics of the Earth maintains the original philosophy of this classic graduate textbook on fundamental solid earth geophysics, while being completely revised, updated, and restructured into a more modular format to make individual topics even more accessible. Building on the success of previous editions, which have served generations of students and researchers for nearly forty years, this new edition will be an invaluable resource for graduate students looking for the necessary physical and mathematical foundations to embark on their own research careers in geophysics. Several completely new chapters have been added and a series of appendices, presenting fundamental data and advanced mathematical concepts, and an extensive reference list, are provided as tools to aid readers wishing to pursue topics beyond the level of the book. Over 140 student exercises of varying levels of difficulty are also included, and full solutions are available online at www.cambridge.org/9780521873628.
