Book Description
The major emphasis of this book is on physical mechanisms and sources of the ULF/ELF natural electromagnetic fields noises. In the course of this text, some of these mechanisms of magnetospheric origin will be treated in detail and others in a more sketchy fashion, while the global electromagnetic resonances excited by lightning activity and other sources are the priority. The interested reader is referred to the books cited in the text for details about the ULF/ELF fields of magnetospheric origin. Much emphasis is put on studies of electromagnetic phenomena caused by rock deformation/fracture including the ULF/ELF effects possibly associated with tectonic activity, earthquakes and other natural disasters. One of the challenges of this research is to fully understand electromagnetic effects and physical processes in the rocks deep in the Earth’s crust.

Book Description
IN view of the growing interest in spectroscopy at radio and micro wave frequencies, and the increasing number of its applications to both physics and chemistry, it was thought that a general outline of the subject for non-specialists might be of some value. Research in this field is still expanding, but is now sufficiently developed for a critical review to be made both of its main applications and of the techniques that are used in this wavelength region. A broad approach has been taken, and the similarity and inter relation of the different branches have been stressed, as well as their general setting in spectroscopy as a whole. In this way it is hoped that the book will be of interest to many research workers and students who, although not directly concerned with the subject, would like to obtain a general picture of its methods and applica tions. At the same time considerable space has been given to the design of experimental apparatus and equipment, so that those wishing to set up such spectroscopes should be able to find much useful and detailed information.

Book Description
Beginning with the development of finite difference equations, and leading to the complete FDTD algorithm, this is a coherent introduction to the FDTD method (the method of choice for modeling Maxwell's equations). It provides students and professional engineers with everything they need to know to begin writing FDTD simulations from scratch and to develop a thorough understanding of the inner workings of commercial FDTD software. Stability, numerical dispersion, sources and boundary conditions are all discussed in detail, as are dispersive and anisotropic materials. A comparative introduction of the finite volume and finite element methods is also provided. All concepts are introduced from first principles, so no prior modeling experience is required, and they are made easier to understand through numerous illustrative examples and the inclusion of both intuitive explanations and mathematical derivations.
