Download or read book Measurements of the Dielectric Properties of Wet Snow Using a Microwave Technique written by Bruce D. Sweeny and published by . This book was released on 1974 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accurate method of measuring liquid water in snow covers is required to determine the properties of wet snow. The dielectric properties of wet snow must be utilized to adequately measure its liquid water content. In this study the effect of liquid water on the complex dielectric constant of natural snow is determined in the microwave frequency range. Deloor's method for calculating the dielectric constant for mixtures and the results of waveguide experiments on samples of wet snow and glass beads are used to construct a calibration curve relating the measured dielectric loss factor directly to the water content of wet snow. The results are independent of porosity, past history and chemical impurities. A relation between the effective dielectric constant and the porosity and water content is proposed and tested experimentally. The general nature of this relation is described and suggestions are made for the development of a more precise relation. It is concluded that the dielectric constant is a function of porosity and water content only.

Download or read book Electrical Properties of Rocks written by E. I. Parkhomenko and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently there has been growing interest in the physical properties of rocks. To interpret data on the geophysical fields observed near the Earth's surface, we must know the physical properties of the materials composing the interior. Moreover, the development of geophysical methods (in particular, electrical methods) is necessitating a multiple approach to the study of the physical properties of rocks and minerals. In connection with problems now appearing, the physical properties of rocks must be studied in the laboratory under var ious thermodynamic conditions. Electrical methods of geophysi cal exploration often may require only data obtained at atmos pheric pressure and room temperature, or at temperatures below 100°C. If, however, we have in mind geophysical field observa tions on the composition and state of matter deep in the Earth's crust and mantle, we must conduct laboratory experiments at high pressures and temperatures. For example, in interpreting data from geomagnetic soundings of the mantle, we may need experi mental results on the electrical properties of rocks at pressures of tens of kilobars and temperatures of the order of lOOO°C. In this connection, we must remember that pressure has relatively little effect on the electrical properties of rocks, whereas, tem perature affects them very strongly. v vi FOREWORD At present, while research into the mechanical properties of rocks (relating to the problems of geophysics, geochemistry, geology, and mining) is pressing forward on a wide front, much less work is being done with electrical properties.

Available in PDF, EPUB and Kindle. Book excerpt: Issues relating to the high-K gate dielectric are among the greatest challenges for the evolving International Technology Roadmap for Semiconductors (ITRS). More than just an historical overview, this book will assess previous and present approaches related to scaling the gate dielectric and their impact, along with the creative directions and forthcoming challenges that will define the future of gate dielectric scaling technology. Topics include: an extensive review of Moore's Law, the classical regime for SiO2 gate dielectrics; the transition to silicon oxynitride gate dielectrics; the transition to high-K gate dielectrics (including the drive towards equivalent oxide thickness in the single-digit nanometer regime); and future directions and issues for ultimate technology generation scaling. The vision, wisdom, and experience of the team of authors will make this book a timely, relevant, and interesting, resource focusing on fundamentals of the 45 nm Technology Generation and beyond.
