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 Dielectric Properties of Polymers written by Frank Karasz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the electrical properties of polymers constitutes a substantial fraction of the total research interest in macro molecular behavior. Because of the increasing attention now being paid to theoretical and experimental aspects of the phenomena encountered, a symposium focusing particularly on dielectric behavior was held at the l6lst National Meeting of the American Chemical Society in Los Angeles, California, March, 1971. The authoritative papers in this volume were all presented at this symposium, which was sponsored by the Polymer Division of the American Chemical Society. An obvious advantage of such a collection is that it keep~ together closely related material which would otherwise tend to be dispersed amongst different journals; a further factor of which most authors represented here have taken advantage is that it gives an opportunity to present research in less attenuated form than is now normally possible in journals. I wish to thank all the authors for their uniformly excellent contributions and for their cooperation in the publication of this volume. Thanks are also due to Dr. S. Matsuoka for chairing one of the sessions at the symposium. September, 1971 Frank E. Karasz v LIST OF CONTRIBUTORS B.

This book was released on 2016-03-15 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book a test set for dielectric measurements at 2.45 GHz during curing of polymer composites is developed. Fast reconstruction is solved using a neural network algorithm. Modeling of the curing process at 2.45 GHz using both dielectric constant and dielectric loss factor results in more accurate model compared to low frequency modelling that only uses the loss factor. Effect of various hardeners and different amount of filler is investigated.
