Download or read book Geo Electromagnetism written by James Wait and published by Elsevier. This book was released on 2012-12-02 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geo-Electromagnetism surveys the theoretical concepts and applications of electrical prospecting methods. This book is divided into seven chapters that specifically tackle the basic electromagnetic concepts and the special mathematical functions. This text deals first with the numerical and analytical approaches to delineate earth resistivity principles, followed by a description of the three-layer model. These topics are followed by a discussion on the theory of induced electrical polarization. The subsequent chapters are devoted to relevant electromagnetic theory of low-frequency current flow in conducting with varying fields. The discussion then shifts to the geophysical problems associated with vertical electric dipole sources, with an emphasis on the quasi-static range in which all significant distances are small compared with the free-space wavelength. The last chapters outline the relevant analytical development of the magnetotelluric theory and the theoretical principles of the transient electromagnetic methods used in geophysical exploration. Geophysicists, theoreticians, and undergraduate level students will find this book invaluable.
Download or read book Propagation of SLF ELF Electromagnetic Waves written by Weiyan Pan and published by Springer Science & Business Media. This book was released on 2013-10-12 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the SLF/ELF wave propagation, an important branch of electromagnetic theory. The SLF/ELF wave propagation theory is well applied in earthquake electromagnetic radiation, submarine communication, thunderstorm detection, and geophysical prospecting and diagnostics. The propagation of SLF/ELF electromagnetic waves is introduced in various media like the earth-ionospheric waveguide, ionospheric plasma, sea water, earth, and the boundary between two different media or the stratified media. Applications in the earthquake electromagnetic radiation and the submarine communications are also addressed. This book is intended for scientists and engineers in the fields of radio propagation and EM theory and applications. Prof. Pan is a professor at China Research Institute of Radiowave Propagation in Qingdao (China). Dr. Li is a professor at Zhejiang University in Hangzhou (China).

The behavior of the magnetic and electric fields from a vertical magnetic dipole source at the surface of the earth (after Wait [1951,1955]). earth, the experimental curve so plotted should have the same shape as a portion of the ap propriate theoretical curve, but with the ordinates and abscissas shifted by an amount dependent on the resistivity. The conductivity can be determined from the amount of shift between the field data and the theoretical curve. A detailed description of the curve matching procedure is found in a text by Keller and Frischknecht (1966). The curve matching procedure, though used, has several disadvantages. Measurements must be made over a diagnostic portion of the theoretical curve, one in which there is some curvature, so that the amount of shift required to make a match can be determined uniquely. This means that the approximate conductivity of the earth must be known when measurements are made. Secondly, determination of a single value of conductivity requires measurements made over a wide range of frequencies. This would appear to be wasteful of data, inasmuch as the equations indicate that a single measurement at a single frequency should be enough to de termine conductivity.
