Metamaterials have established themselves as one of the most important topics in physics and engineering, and have found practical application across a wide variety of fields including photonics, condensed matter physics, materials science, and biological and medical physics. This modern and self-contained text delivers a pedagogical treatment of the topic, rooted within the fundamental principles of nanophotonics. A detailed and unified description of metamaterials and metasurfaces is developed, beginning with photonic crystals and their underlying electromagnetic properties before introducing plasmonic effects and key metamaterial configurations. Recent developments in research are also presented along with cutting-edge applications in the field. This advanced textbook will be invaluable to students and researchers working in the fields of optics and nanophotonics.

This self-contained book gives fundamental knowledge about scattering and diffraction of electromagnetic waves and fills the gap between general electromagnetic theory courses and collections of engineering formulas. The book is a tutorial for advanced students learning the mathematics and physics of electromagnetic scattering and curious to know how engineering concepts and techniques relate to the foundations of electromagnetics.

This book is about analytical modeling and understanding of material layers, composites, artificial materials and metamaterials. It explains electromagnetic properties of new artificial electromagnetic surfaces and metamaterials, especially size-dependent phenomena in materials, materials with predefined, engineered, and electrically controllable properties, backward-wave or double negative materials and novel prospective devices like, for example, the perfect lens.

ERRATA

This book is about the key elements of the millimeter-wave technology: various millimeter-wave waveguides, waveguide transitions, and devices. The book can serve both as a tutorial presenting the basic theory and the main experimental techniques necessary for the work with millimeter-wave waveguides and millimeter-wave devices, as well as a monograph presenting new developments in this field. Examples show the use of millimeter-wave waveguides in the design of microwave devices and antennas.

More info and order form

Concentrating on the most recent information in the worlds of microwave and optical technology, solid state physics and plasma physics the authors bring the literature current and up-to-date."Electromagnetics of Bi-Anisotropic Materials" focuses on fully bi-anisotropic materials and their microwave applications. These applications are normally found in antennas and scattering, microwave and optical technology, solid state physics and plasma physics. This book also contains a wealth of material regarding the use of spatially dispersive materials and shows how the use of spatially dispersive media provides many new and exciting possibilities in the design of new materials.

Book contents

This book describes how chiral and BI media affect electromagnetic fields and wave propagation, how to apply the theory to basic problems in waveguide, antenna, and scattering analysis, effective methods of measurement, and solutions to electromagnetic problems involving interaction between complex materials and microwave applications.
