One of us (FAB) published a book Problems in Electronics with Solutions in 1957 which became well established and ran to five editions, the last revised and enlarged edition appearing in 1976. When the first edition was written it covered almost the complete undergraduate electronics courses in engin eering at universities. One book, at a price students can afford, can no longer cover an undergraduate course in electronics. It has therefore been decided to produce a book covering one important section of such a course using the experience gained and a few problems from previous editions of Problems in Electronics with Solutions. The book is based largely on problems collected by us over many years and given to undergraduate electronic and electrical engineers. Its purpose is to present the problems, together with a large number of their solutions, in the hope that it will prove valuable to undergraduates and other teachers. It should also be useful for Master's degree students in electronic and electrical engineering and physics, research workers, engineers and scientists in industry and as a reference source."

Die mobile Funkkommunikation ist einer der Wachstumsmarkte unserer Zeit. Fur die Planung zellularer Mobilfunknetze werden dabei verlasstliche Werkzeuge benoetigt, deren Benutzung und Weiterentwicklung nur bei Kenntnis aller Grundlagen und der verwendeten Loesungsverfahren erfolgreich sein kann. Der vorliegende Text versucht, diese grundlegenden Kenntnisse fur einige der wesentlichen Teilaufgaben in der Funknetzplanung zu vermitteln. In der Vielzahl ausgezeichneter Bucher zu den primar nachrichtentechnischen Aspekten des Mobilfunks wird der Beschreibung und Analyse des Funkkanals zwischen den Antennentoren ein vergleichsweise geringer Rahmen beigemessen. Ziel des vorliegenden Buches ist es, diese Lucke zu fullen. Da sich die Charakterisierung des Funkkanals fur verschiedene Funksysteme nicht oder nur wenig unterscheidet, lassen sich die meisten der eroerterten Grundlagen und Verfahren auch auf andere Funksysteme, wie z.B. Rundfunk oder Richtfunk, anwenden.

In recent decades, there has been a phenomenal growth in the field of photonic crystal research and has emerged as an interdisciplinary area.

The domain of metamaterials now covers many area of physics: electromagnetics, acoustics, mechanics, thermics, or even seismology. Huge literature is now available on the subject but the results are scattered. Although many ideas and possible applications have been proposed, which of these will emerge as a viable technology will only unfold with time. This book covers the fundamental science behind metamaterials, from the physical, mathematical, and numerical points of view, focusing mainly on methods. It concentrates on electromagnetic waves, but would also be useful in studying other types of metamaterials. It presents the structure of Maxwell equations, discusses the homogenization theory in detail, and includes important problems on resonance. It has an entire section devoted to numerical methods (finite elements, Fourier modal methods, scattering theory), which aims to motivate a reader to implement them. The book is not written as a collection of independent chapters but as a textbook with a strong pedagogical flavor.

This book presents a modern theory of so-called weak spatial dispersion (WSD) in composite media of optically small inclusions without natural magnetism and optical nonlinearity. WSD manifests in two important phenomena called bianisotropy and artificial magnetism, whose microscopic origin is thoroughly studied in this book. The theory of this book is applicable to the natural media with WSD, such as chiral materials. However, emphasis is given to artificial media, too, with the idea to engineer needed electromagnetic properties. The text describes a homogenization model of effectively continuous media with multipole electromagnetic response, taking into account the interface effects. Another model is developed for so-called metamaterials in which artificial magnetism can be a resonant phenomenon and may result in the violation of Maxwell's boundary conditions and other challenges. The book will hopefully improve the understanding of WSD and help readers to correctly describe and characterize metamaterials.
