Dielectric Materials And Electrostatics

An introduction to the physics of electrical insulation, this book presents the physical foundations of this discipline and the resulting applications. It is structured in two parts. The first part presents a mathematical and intuitive approach to dielectrics; various concepts, including polarization, induction, forces and losses are discussed. The second part provides readers with the keys to understanding the physics of solid, liquid and gas insulation. It comprises a phenomenological description of discharges in gas and its resulting applications. Finally, the main electrical properties of liquids and solids are presented, in order to explain the phenomena of electrical degradation, dissipation and breakdown. Contents 1.

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.

This book provides an overview of key dielectric materials for capacitor technology. It covers preparation and characterization of state-of-the art dielectric materials including ceramics, polymers and polymer nanocomposites, for popular applications including energy storage, microwave communication and multi-layer ceramic capacitors.

Electrostatic stresses are a fascinating field where materials science, continuum mechanics and electrical engineering all come together. This is one of the reasons why the study of these so-called Maxwell stresses is so interesting.

Examines the influences of electric fields on dielectric materials and explores their distinctive behavior through well established principles of physics and engineering and recent literature on dielectrics. Facilitates understanding of the space charge phenomena in the nonuniform fields. Contains more than 800 display equations.

This is the first of two papers in which an attempt is made to clarify the standard theories of dielectrics and of permeable materials, and in particular, to clarify the meanings of D and H, two vectors that are frequently defined unsatisfactorily in the literature. It is intended to introduce certain well-defined postulates, and then to show that these postulates are equivalent to the implicit and sometimes camouflaged assumptions that underlie the usual treatments. This first article treats dielectrics and D; a later one will treat permeable matter and H. (Author).
