Electrical Spectroscopy of Earth Materials provides detailed coverage of theoretical and experimental methods of electrical spectroscopy of Earth materials, based on first-hand research and extensive data. The book includes actual data sets and specific explanations for the methods used in obtaining and analyzing the data, including graphical displays of results. It describes the electrical properties of various soil samples and offers both theory and techniques for researchers to apply to their own research. Including examination of the practical aspects of electrical spectroscopy measurements and extensive computer-readable data, Electrical Spectroscopy of Earth Materials is a unique resource for geophysicists to save both time and effort in understanding and analyzing Earth materials and soil properties.

Tsylya M. Levitskaya is a Researcher for the Laboratory for Advanced Subsurface Imaging at the University of Arizona. She came to the United States in 1992 from Russia, where she received her M.S. in electrical engineering from the Polytechnic Institute (Tomsk), and a Ph.D. in physics and mathematics from the Institute of Macromolecular Compounds, USSR Academy of Science (Leningrad). From 1978 to 1991, she worked in geophysics for the Siberian Institute of Geology, Geophysics and Mineral Resources (Novosibirsk), applying the dielectric spectroscopy method for studying earth materials in a frequency range from 0.01 Hz to 100 MHz. Her current research interests include electrical properties of soils in the frequency range 1 kHz to 1 GHz. Ben K. Sternberg is currently Professor and Director of the Laboratory for Advanced Subsurface Imaging at the University of Arizona. He received his B.S. in physics and his M.S. and Ph.D. in geophysics from the University of Wisconsin, Madison. He has worked at Conoco, Inc., Barringer Resources, and Phoenix Geophysics. He has been Professor and Director of the Laboratory for Advanced Subsurface Imaging (LASI) at the University of Arizona since 1986. His research interests include electrical methods geophysics, instrumentation, high-resolution imaging methods, and integration of multiple data sets to solve geoscience problems.
