Description

In the field of electromagnetic and/or optical waves, the concept of “artificial material” covers any fabricated device, be it metallic, dielectric or metal-dielectric, enabling a varyingly complex control of wave propagation in a chosen wavelength range. A common point to all approaches is that the structural scale of the building blocks of a new material is proportional to its operating wavelength. From this first principle stem two relatively distinct research paths, “photonic crystals” (or photonic/electromagnetic materials with a band gap) and “metamaterials”. This book discusses these artificial materials, focusing on photonic crystals (PC) and metamaterials (MM). The first part is devoted to design concepts: negative permeability and permittivity for negative refraction, periodic structures, transformation optics. Part 2 concerns PC and MM in a band gap regime: from cavities and guides to high impedance surfaces. Abnormal refraction, less than one and negative, in PC and MM are studied in the third part, addressing super-focusing and cloaking. Then, applications for telecommunications, lasers and imaging systems are explored.

About the Authors

Olivier Vanbésien received a doctorate in quantum devices in 1991. He then joined the Institut d’Electronique, de Microélectronique et de Nanotechnologie (IEMN) and was appointed Professor of Electronics at Lille University in France in November 2000. His interests concern metamaterials and photonic crystals, exploring abnormal refraction from terahertz down to optics.
