Modern Applications Of Electrostatics And Dielectrics

Electrostatics and dielectric materials have important applications in modern society. As such, they require improved characteristics. More and more equipment needs to operate at high frequency, high voltage, high temperature, and other harsh conditions. This book presents an overview of modern applications of electrostatics and dielectrics as well as research progress in the field.

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.

This book describes innovative agricultural methods using thermal and non-thermal microwave or plasma energies. Humans that were nomadic in the past can now stably obtain food by developing agriculture. Cities were formed as a result of remarkable development. Later, chemicals were introduced to agriculture to stabilize the food supply further. Natural products were initially used, but various artificial compounds have been developed for agriculture since the 1900s. To further improve crop productivity and diversification, gene recombination (genetic engineering) using biotechnology has progressed in recent years and continues to develop further. However, these technologies contain pesticide residues and pose safety risks. The innovative new agriculture explained in this book is based on the use of microwaves and plasma that do not rely on chemicals and genetic modification. This is one of the first books focusing on the agricultural usage of microwaves. In addition, it is a technical book that incorporates plasma into agriculture from this perspective. The book covers microwaves and plasmas, which are completely different fields. Thus, it will be attractive to many readers who want to acquaint themselves with these alternative technologies and implement them. This book will be useful to a broad audience including researchers and technicians at Universities and practitioners in industries. It is made accessible to readers across different fields by including abundant figures and by limiting the use of equations to the possible extent.

This classic set is a crucial landmark in the development of the field of dielectrics -- a field belonging not only to physics or chemistry, but also to modern electrical engineering. Featuring comprehensive coverage that has remained unsurpassed even by today's standards, this set's timeless value makes it a must-have for anyone with a serious interest in dielectric engineering.

This book constitutes the refereed proceedings of the 11th International Conference on Haptic and Audio Interaction Design, HAID 2022, held in London, UK, in August 2022. The 13 full papers presented were carefully reviewed and selected from 19 submissions that were sent for peer review. The papers are organized in topical sections on accessibility, perception, design and applications, and musical applications.
