Book Description
Antennas in Matter provides both an introduction to and a comprehensive description of the properties of antennas and probes embedded within or near material bodies such as the earth, the ocean, or a living organism. The theory and application of antennas designed to transmit and receive information between points above the earth's surface are for the most part well understood. This book presents a full treatment of a sequence of research that has become increasingly important in recent years--the use of underground antennas for communication with miners and subway trains and for the geophysical exploration of the earth's crust; underwater antennas; antennas embedded in or near living organisms for biomedical and diagnostics in tissue and layered media with electromagnetic properties as diverse as those of fat, muscle, and bone. The book has been designed to serve a dual purpose: the first and third parts, covering fundamentals and measurements, form a self-contained introduction for undergraduates and researchers in geophysics and bioengineering; the second part provides a detailed presentation of the theory for graduate students and researchers in electrical engineering and physics. The approach integrates analytical, numerical, and experimental methods for the solution of a variety of problems involving antennas and electromagnetic wave propagation in or near matter.

Book Description
Why yet another book on antennas ? The aim of the authors was to offer a didactic text appropriate for advanced graduate students, as well as a practical work for practicing engineers; to combine a solid theoretical treatment with a practical development which should allow the serious reader to undertake antenna design from fIrst principles. To accomplish these goals, the authors bring together their contributions from both industry and the academic environment. The developments of the various topics start at a level which is accessible to a novice in the speciality, but give a treatment which culminates at an advanced level. Another important feature of the book is its use of practical examples illustrating real engineering problems and designs. In most cases, the explanation is sufficient to grasp the principles of operation of the related equipment, and, where appropriate, the reader is referred to a relevant bibliography for more complete and hence more sophisticated methodologies of design. Of particular note are the chapters on specialist subjects such as antennas and signal theory, and signal processing antennas, showing how the antenna may be combined with signal processing techniques in imaging applications, in angular superresolution, and in adaptive arrays to suppress interference and jamming. Another example is the chapter on the use of polarimetry to enhance the wealth of information which may be extracted, for example, from radar signals.
