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 Terahertz Spectroscopy written by Jamal Uddin and published by BoD – Books on Demand. This book was released on 2017-03-13 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The terahertz regime of the electromagnetic spectrum was largely unexplored due to the lack of technology needed to generate and detect the radiation. However, in the last couple of decades, there has been a dramatic increase in tools needed to harness the radiation. This remarkable progress made in the development of terahertz sources, components, and detectors has resulted in an ever-increasing inquisitiveness of the applications of terahertz technology in a wide range of fields including medicine, pharmaceuticals, security, sensing, and quality assurance. This book, Terahertz Spectroscopy - A Cutting Edge Technology, presents an overview of the recent advances in terahertz technology and their application in a vast array of fields. The scientists and students are encouraged to read and share the content of this volume. The book also provides a good starting point for researchers who are new to the terahertz regime. The various chapters of the book have been written by renowned scientists in different parts of the world who are at the forefront of terahertz research fields. It is our (InTech publisher, editor, and authors) hope that this book will enhance knowledge and stimulate more interest and future research in terahertz technology.

Download or read book Electromagnetic Theory and Wave Propagation written by S. N. Ghosh and published by CRC Press. This book was released on 2002 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the fundamental concepts of Maxwell remain for the most part unchanged since their inception, electromagnetic theory has continued to evolve, extending, most significantly, to shorter and shorter wavelengths. This has revealed many of nature's mysteries. And led to a myriad of applications that have literally changed our world. The second edition of Electromagnetic Theory and Wave Propagation begins by presenting the basic concepts of electromagnetic theory, then explores the field's extended areas primarily discovered after World War II. The author elaborates on the work of pioneer investigators, particularly with respect to the identity of light and electromagnetic waves and then derives the fundamental laws of optics from electromagnetic considerations. He has also added several new topics including meteor astronomy, remote sensing and, most notably, discussions on relativistic electrodynamics.

Available in PDF, EPUB and Kindle. Book excerpt: The report relates to utility of imaging radars for arctic surface guidance. The program involves field measurements of backscatter from snow, ice and sea ice for a wide variety of meteorological and surface conditions. Laboratory measurements of the complex dielectric constant are presented also, to enable the separation of the roughness contribution to the backscatter. During the first seven months of the program, the dielectric properties of sea ice were measured in the laboratory from 36 to 40 GHz, over a representative range of temperatures, salinities, and orientation. The real part of the dielectric constant is close to 3 for most conditions, but the loss tangent can vary over three orders of magnitude, depending upon the temperature and salinity. Under most conditions, an incident wave of 1 cm wavelength would penetrate less than one meter into the sea ice. Strong distinction of freshly-formed sea ice from old sea ice appears likely. Backscatter from sea ice is currently being measured. Distinction of rough and smooth surfaces is possible, based upon preliminary interpretation of the data. (Author).
