This book is based on the updated versions of a lively mixture of tutorials, topical papers, and scientific and technological contributions collected from the International URSI Symposium on Environmental and Space Electromagnetics held in Tokyo on 4-6 September, 1989. It was sponsored by the International Union of Radio Science (URSI) as an activity of Commission E (Chairman: present editor) preceding the URSI General Assembly in Prague, Czechoslovakia in 1990. The aim was an exchange of information and views to highlight the state of the art in radio science and interdisciplinary areas. Along this line, the editor has attempted to cover quite new, novel or unconventional subjects besides more traditional or conventional ones. Although a great many subjects have apparently been covered, this book has been edited so the reader can find some common concepts or views presented. On this basis, a group of many subjects can be treated in a unified fashion, and new ideas and views can be gained as a most valuable addition to current knowledge. This is one of the major features of this volume that cannot be found in any of the monographs or proceedings that cover a narrow range oflimited topics. Its broad scope does not stand for presentation in a superficial and shallow manner, but stands for a strong focus on the search for a common nature in basic concepts or views in apparently diverse subjects, and a focus on the advanced or innovatory nature of each contribution.

Electromagnetic compatibility and regulatory compliance issues are subjects of great importance in electronics engineering. Avoiding problems regarding an electronic system's operation, while always important, is especially critical in space missions and satellite structures. Many problems can be traced to EM field disturbances as interference from unintended sources and other electromagnetic phenomena. As a result, stringent requirements are to be met in terms of electromagnetic emissions levels. The inclusion of this electromagnetic environment in the design of a multimillion mission can lead to a system that is able to withstand whatever challenge the environment throws at it. Failure to do so may lead to important data corruption or loss, destruction of expensive instruments, waste of resources, and even a total mission failure. Research in this area focuses on the studying of the applications of electromagnetic compatibility and electromagnetic interference in the space industry. Recent Trends on Electromagnetic Environmental Effects for Aeronautics and Space Applications will provide relevant theoretical frameworks and the latest empirical research findings in electromagnetic compatibility and electromagnetic interference (EMC/EMI) for the aerospace industry. This book examines all the necessary information for all matters that can possibly affect the system design of a spacecraft and can be a useful reference to space system engineers and more. While highlighting topics such as artificial intelligence, electromagnetic testing, environmental shielding, and EMC modelling techniques, this book is ideal for professionals, spacecraft designers, science and data processing managers, electrical and mechanical engineers, EMC testing engineers, and researchers working in the aerospace industry along with practitioners, researchers, academicians, and students looking for necessary information for all the matters that can possibly affect the system design of a spacecraft.

This book contains papers from the URSI International Symposium on Environmental and Space Electromagnetics and includes both tutorials and original presentations. The aim of the symposium was to bring together radio, atmospheric, and space scientists and engineers with different backgrounds in order to exchange information and views on new areas, thus highlighting the current state of research in radio science and interdisciplinary areas. The book covers traditional problems as well as new unconventional ones, many of which have never been discussed in an open forum before. The book covers novel topics such as spacecraft EM environments; terrestrial and extraterrestrial noise environments; planetary lightning and emissions, including the results from the Voyager-Neptune flyby; lightning and nuclear electromagnetic pulses; triggered and ball lightning; extraterrestrial noise and plasmas; seismoelectric emissions; and meteorologico-electric phenomena and EHD (electrohydrodynamics) including atmospheric EHD vortex phenomena which have drawn a worldwide public interest quite recently. More traditional subjects include man-made radio noise environment and EMC; space communication, measurement and frequency man- agement; noise and communication statistics; geomagnetic induction and radio-plasma noise; lightning; atmospherics, whistlers and emissions; and VLF/ELF EM environments. The book thus spans a wide range of radio science and will be a valuable source of new ideas, particularly in interdisciplinary areas of meteorologico-electric phenomena.

In the aerospace industry, avoiding operating issues, especially in regard to space missions and satellite structures, is crucial. The vast majority of these issues can be traced to disturbances in the electromagnetic fields used. Electromagnetic Compatibility for Space Systems Design is a critical scholarly resource that examines the applications of electromagnetic compatibility and electromagnetic interference in the space industry. Featuring coverage on a wide range of topics, such as magnetometers, electromagnetic environmental effects, and electromagnetic shielding, this book is geared toward managers, engineers, and researchers seeking current research on the applications of electromagnetic technologies in the aerospace field.

The COSPAR Colloquium on Solar-Terrestrial Magnetic Activity and Space Environment (STMASE) was held in the National Astronomy Observatories of Chinese Academy of Sciences (NAOC) in Beijing, China in September 10-12, 2001. The meeting was focused on five areas of the solar-terrestrial magnetic activity and space environment studies, including study on solar surface magnetism; solar magnetic activity, dynamical response of the heliosphere; space weather prediction; and space environment exploration and monitoring. A hot topic of space research, CMEs, which are widely believed to be the most important phenomenon of the space environment, is discussed in many papers. Other papers show results of observational and theoretical studies toward better understanding of the complicated image of the magnetic coupling between the Sun and the Earth, although little is still known little its physical background. Space weather prediction, which is very important for a modern society expanding into out-space, is another hot topic of space research. However, a long way is still to go to predict exactly when and where a disaster will happen in the space. In that sense, there is much to do for space environment exploration and monitoring. The manuscripts submitted to this Monograph are divided into the following parts: (1) solar surface magnetism, (2) solar magnetic activity, (3) dynamical response of the heliosphere, (4) space environment exploration and monitoring; and (5) space weather prediction. Papers presented in this meeting but not submitted to this Monograph are listed by title as unpublished papers at the end of this book.
