Dielectric Matter And The Vector D

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).

Principles of Dielectric Logging Theory covers the theory of dielectric logging - from first principles to development of new tools - for those involved in the design, development and interpretation of dielectric logging. Dielectric logging has recently experienced a revival in the oil and gas industry and is now considered a preferred method for estimating the saturation of reservoirs. Topics covered in this book include the use of dielectric tools in different types of fields, interpretation methods, the Maxwell phenomena, and how to develop new dielectric tools for future use. Users will find this book includes enough detail that newcomers, seasoned professionals and researchers find it useful. Covers both the theory and applications of dielectric logging Provides comprehensive guidance on how to develop dielectric tools Explains what physically takes place in the presence of a dielectric probe

The purpose of the report is to provide a new clarity of insight into concepts that are involved in the design and understanding of devices which have importance in a wide variety of Air Force applications. The formulas derived herein provide new tools for clarifying the mode of operation and optimizing the performance of devices that involve magnetic components. A previous discussion of dielectric matter is extended to the problem of magnetic dipolar matter. The calculation of the external field of a sample of such matter by Amperian currents is reviewed, and the meaning of the average internal field that they can be shown to correctly predict is discussed.

The "Dictionary of Physics" is a major reference source in the vast and dynamic field of physics that caters for both the undergraduate and graduate student. Spanning the space between the primary literature and educational texts, it encompasses 16,000 entries and 1.8 million words in four volumes.

An unprecedented look into the basic physics, chemistry, and technology behind the LCD Most notably used for computer screens, televisions, and mobile phones, LCDs (liquid crystal displays) are a pervasive and increasingly indispensable part of our lives. Providing both an historical and a business-minded context, this extensive resource describes the unique scientific and engineering techniques used to create these beautiful, clever, and eminently useful devices. In this book, the history of the science and technology behind the LCD is described in a prelude to the development of the device, presenting a rational development theme and pinpointing innovations. The book begins with Maxwell's theory of electromagnetism, and the ultimately profound realization that light is an electromagnetic wave and an electromagnetic wave is light. The power of mathematical physics thus was brought to bear upon the study of light, and particularly the polarization of light by material bodies, including liquid crystals. After a brief historical description of polarization, a physical interpretation provides substance to the mathematical concepts. Subsequent chapters cover: Thermodynamics for liquid crystals The Maier-Saupe mean field, phenomenological, static continuum, and dynamic continuum theories The transistor and integrated circuit Glass, panels, and modules The calculus of variations The active matrix Semiconductor fabrication The global LCD business Additionally, the book illustrates how mathematics, physics, and chemistry are put to practical use in the LCDs we use every day. By describing the science from an historical perspective and in practical terms in the context of a device very familiar to readers, the book presents an engaging and unique view of the technology for everyone from science students to engineers, product designers, and indeed anyone curious about LCDs. Series Editor: Anthony C. Lowe, The Lambent Consultancy, Braishfield, UK The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics.
