In general, a dielectric is considered as a non-conducting or insulating material (such as a ceramic or polymer used to manufacture a microelectronic device). This book describes the laws governing all dielectric phenomena. A unified approach is used in describing each of the dielectric phenomena, with the aim of answering "what?", "how?" and "why" for the occurrence of each phenomenon; Coverage unavailable in other books on ferroelectrics, piezoelectrics, pyroelectrics, electro-optic processes, and electrets; Theoretical analyses are general and broadly applicable; Mathematics is simplified and emphasis is placed on the physical insight of the mechanisms responsible for the phenomena; Truly comprehensive coverage not available in the current literature.
