An accurate quantitative picture of electric field distribution is essential in many electrical and electronic applications. In composite dielectric configurations composed of multiple dielectrics, anomalous or unexpected behavior of electric fields may appear when a solid dielectric is in contact with a conductor or another solid dielectric. The electric field near the contact point may become higher than the original field not only in the surrounding medium but also in the solid dielectric. Theoretically it may become infinitely high, depending on the contact angle. Although these characteristics are very important in a variety of applications, they have been clarified only recently using analytical and numerical calculation methods, and this is the first book to cover these new findings. Electric Fields in Composite Dielectrics and Their Applications describes the fundamental characteristics and practical applications of electric fields in composite dielectrics. The focus is on the field distribution (and the resultant force when appropriate) near points of contact. Applications include insulation design of high-voltage equipment with solid insulating supports, utilization of electrostatic force on dielectric particles in electrophotography and electrorheological fluids, and others. Electric Fields in Composite Dielectrics and Their Applications also explains the calculation methods used to analyze electric fields in composite dielectrics.

With the constant emergence of new research and application possibilities, gaseous electronics is more important than ever in disciplines including engineering (electrical, power, mechanical, electronics, and environmental), physics, and electronics. The first resource of its kind, Gaseous Electronics: Tables, Atoms, and Molecules fulfills the author’s vision of a stand-alone reference to condense 100 years of research on electron-neutral collision data into one easily searchable volume. It presents most—if not all—of the properly classified experimental results that scientists, researchers, and students require for a theoretical and practical understanding of collision properties and their impact. An unprecedented collection and analysis of electron neutral collision properties This book follows a new user-friendly format that enables readers to easily retrieve, analyze, and apply specific atomic/molecular information as needed. In his previous work, Gaseous Electronics: Theory and Practice, the author first explored electron–neutron interactions. To clarify the complex fundamental processes involved, he cited as much experimental data on atoms and molecules as limited space would allow. Completing that task, this handy reference more fully compiles essential revised data on more than 420 atoms and molecules, arranging it into easily digestible chapters, sections, and appendices. Analysis parameters include total scattering, ionization, excitation, attachment cross sections, ionization and attachment coefficients, attachment rates, and ion drift velocity. Some recent research areas in gaseous electronics include: Environmentally efficient and protective lighting devices Plasma research for power generation and space applications Medical applications (some involving skin treatment and healing) Written entirely in SI units, the book includes hundreds of tables, figures, and specially drawn charts, with data expressed in both tabular and graphical form. Each chapter stands independently and contains references for further research.

Written by leading experts in the field, the first edition of this textbook was the first of its kind to address numerous potential applications such as the technology of high-voltage insulation in pulsed inhomogeneous fields, and applications related to cavitation development in liquid dielectrics, treatment of different materials and plasma medicine. This second edition addresses the development of the theory over the past few years and features extensive revisions, as well as some expanded chapters. A new inclusion is an explanation of how the critical pressure at which cavitation is initiated is determined according to the surface tension coefficient at the boundary of small nanovoids and microbubbles. Discussion of the quantum mechanical nature of the cavitation inception in liquid helium is also provided, along with the derived values of critical negative pressure for the appearance of cavitation, and its characteristics at low temperatures.

The chase and ultimate destruction of the German Battleship Bismarck in May 1941 is one of the epic stories of the naval side of World War II. It is told here in detail for the first time in English, full use having been made of the information now available from both British and German sources.--Dust jacket.

The object of this book is to provide a comprehensive reference source for the numerous scientific communities (engineers, researchers, students, etc.) in various disciplines which require detailed information in the field of dielectric materials. Part 1 focuses on physical properties, electrical ageing, and modeling - including topics such as the physics of charged dielectric materials, conduction mechanisms, dielectric relaxation, space charge, electric ageing and end of life (EOL) models, and dielectric experimental characterization. Part 2 examines applications of specific relevance to dielectric materials: insulating oils for transformers, electro-rheological fluids, electrolytic capacitors, ionic membranes, photovoltaic conversion, dielectric thermal control coatings for geostationary satellites, plastics recycling and piezoelectric polymers.
