Book Description
Physics of Dielectrics for the Engineer is a systematic attempt to clarify and correlate advanced concepts underlying the physics of dielectrics. It reviews the basics of electrostatics, the different models for the polarizability of atoms and molecules, and the macroscopic permittivity. It also discusses the behavior of matter in an alternating field in relation to complex permittivity, the interactions between field and matter, dissipative effects under high electric fields, the wide-gap semiconductor model, the types of charge carriers, and the main disruptive processes. Organized into three parts encompassing 12 chapters, this volume begins with an overview of the physical concepts involved in the behavior of insulating materials subjected to high electric fields. It then explores the potential of a group of charges, and dipoles induced in an applied field. The book explains statistical theories of dipole orientation in an applied field and theories relating molecular and macroscopic quantities. The propagation of an electromagnetic wave, dipole relaxation of defects in crystal lattices, and space-charge polarization and relaxation are also discussed. The book explains the uni-dimensional polar lattice, intrinsic and impurity conduction in wide-gap semiconductors, thermal runaway, and collision breakdown. Many problems with corresponding solutions are included to assist the reader. This book will benefit electrical engineers, as well as electrical engineering students, scientists, and technicians.

Book Description
This text/reference provides students, practicing engineers, and scientists with the fundamental physical laws and modern applications used in industry. Unlike many of its competitors, modern physics theory (e.g., quantum physics) and its applications are discussed in detail, including laser techniques and fiber optics, nuclear fusion, digital electronics, wave optics, and more. An extensive review of Boolean algebra and logic gates is also included. Because of its in-text examples with solutions and self-study exercise sets, the book can be used as a refresher for engineering licensing exams or as a full year course. It emphasizes only the level of mathematics needed to master concepts used in industry.

Book Description
Dielectrics in Electric Fields explores the influence of electric fields on dielectric—i.e., non-conducting or insulating—materials, examining the distinctive behaviors of these materials through well-established principles of physics and engineering. Featuring five new chapters, nearly 200 new figures, and more than 800 new citations, this fully updated and significantly expanded Second Edition: Analyzes inorganic substances with real-life applications in harsh working conditions such as outdoor, nuclear, and space environments Introduces methods for measuring dielectric properties at microwave frequencies, presenting results obtained for specific materials Discusses the application of dielectric theory in allied fields such as corrosion studies, civil engineering, and health sciences Combines in one chapter coverage of electrical breakdown in gases with breakdown in micrometric gaps Offers extensive coverage of electron energy distribution—essential knowledge required for the application of plasma sciences in medical science Delivers a detailed review of breakdown in liquids, along with an overview of electron mobility, providing a clear understanding of breakdown phenomena Explains breakdown in solid dielectrics such as single crystals, polycrystalline and amorphous states, thin films, and powders compressed to form pellets Addresses the latest advances in dielectric theory and research, including cutting-edge nanodielectric materials and their practical applications Blends early classical papers that laid the foundation for much of the dielectric theory with more recent work The author has drawn from more than 55 years of research studies and experience in the areas of high-voltage engineering, power systems, and dielectric materials and systems to supply both aspiring and practicing engineers with a comprehensive, authoritative source for up-to-date information on dielectrics in electric fields.
