Negative-Refraction Metamaterials: Fundamental Principles and Applications pdf epub mobi txt 电子书 下载 2025

Learn about the revolutionary new technology of negative-refraction metamaterials

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.
