This book mainly introduces how to measure and analyze electric charge accumulation in Dielectrics. By using the PEA and Q(t) methods with the Quantum Chemical Calculation, the charge characteristics of solid dielectrics under different situations are analyzed, which are never discussed in detail by other books. The book contains a large number of experimental and simulation data as illustrations, and thus the reader can understand the theory in the book very easily. Meanwhile, the reader can learn how to use the two methods to measure charge behavior under different conditions and analyze the charge phenomena by Quantum Chemical Calculation.

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.
