The author describes analytic and numerical methods, providing powerful and sophisticated solutions to electromagnetic problems. These problems are presented as realistic models of actual situations which arise in the areas of optics, radio wave propagation, geophysical prospecting, nondestructive testing, biological sensing and remote sensing.
This book is intended for graduate students, practising engineers, researchers in electromagnetic wave theory. Engineers, physicists, geophysicists involved in remote sensing especially.
Subjects Electromagnetic fields. Electromagnetic waves. Elektromagnetisches Feld. Inhomogenes Medium. Bibliographic information. Additionally, demonstrations are given, so the book can be used to teach post-graduate courses. Examines the fundamentals of wave propagation in anisotropic, anelastic and porous media Presents all equations and concepts necessary to understand the physics of wave propagation, with examples Emphasizes geophysics, particularly, seismic exploration for hydrocarbon reservoirs, which is essential for exploration and production of oil.
Part one covers fundamentals of electromagnetic wave propagation, radiation, and scattering. It provides ample end-of-chapter problems and offers a page solution manual to help readers check and comprehend their work. The second part of the book explores up-to-date applications of electromagnetic waves—including radiometry, geophysical remote sensing and imaging, and biomedical and signal processing applications.
The book is also a useful reference for engineers and scientists working in fields such as geophysical remote sensing, bio—medical engineering in optics and ultrasound, and new materials and integration with signal processing. These devices include various filters, delay lines, phase shifters, frequency converters, nonreciprocal and nonlinear devices, and others. Magnetostatic Waves in Inhomogeneous Fields examines magnetostatic waves and their distribution in non-uniformly magnetized films and structures.
The propagation of magnetostatic waves in magnetodielectric environments is accompanied by numerous and very diverse physical effects, sharply distinguishing them from ordinary electromagnetic waves in isotropic media. The authors address dispersion properties and noncollinearity of phase and group velocity vectors, as well as non-reciprocal propagation. Key Features Offers mathematical tools used in the calculation of properties of magnetostatic waves Includes a current literature review of magnetostatic waves and domain structures in garnet—ferrite films Considers the issue of converting magnetostatic waves into electromagnetic ones.
The problems of surface acoustic wave interaction with periodic topographic gratings widely used in filters and resonators are under careful consideration. The most important results of surface wave scattering by local defects such as grooves, random roughness, elastic wedges are given. Different theoretical approaches and practical rules for solving the surface wave problems are presented.
DOI: Popov , I. An asymptotic procedure for the computation of wave fields in two-dimensional laterally inhomogeneous media is proposed. It is based on the simulation of the wave field by a system of Gaussian beams. Each beam is continued independently through an arbitrary inhomogeneous structure.
The complete wave field at a receiver is then obtained as an integral superposition of all Gaussian beams arriving in some neighbourhood of the receiver. The corresponding integral formula is valid even in… Expand. View via Publisher. Save to Library Save. Create Alert Alert. Share This Paper. Background Citations.
