Negative-refraction metamaterials: fundamental principles and applications introduces artificial materials that support the unusual electromagnetic property of negative refraction. readers will discover several classes of negative-refraction materials along with their exciting, groundbreaking applications, such as lenses and antennas, imaging with super-resolution, microwave devices, dispersion-compensating interconnects, radar, and defense. the book begins with a chapter describing the fundamentals of isotropic metamaterials in which a negative index of refraction is defined. in the following chapters, the text builds on the fundamentals by describing a range of useful microwave devices and antennas. next, a broad spectrum of exciting new research and emerging applications is examined, including: * theory and experiments behind a super-resolving, negative-refractive-index transmission-line lens * 3-d transmission-line metamaterials with a negative refractive index * numerical simulation studies of negative refraction of gaussian beams and associated focusing phenomena * unique advantages and theory of shaped lenses made of negative-refractive-index metamaterials * a new type of transmission-line metamaterial that is anisotropic and supports the formation of sharp steerable beams (resonance cones) * implementations of negative-refraction metamaterials at optical frequencies * unusual propagation phenomena in metallic waveguides partially filled with negative-refractive-index metamaterials * metamaterials in which the refractive index and the underlying group velocity are both negative this work brings together the best minds in this cutting-edge field. it is fascinating reading for scientists, engineers, and graduate-level students in physics, chemistry, materials science, photonics, and electrical engineering.
