This book addresses artificial materials including 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.

The second part concerns PC and MM in stop band regime: from cavities, guides to high impedance surfaces. Abnormal refraction, less than one and negative, in PC and MM are studied in a third part, addressing super-focusing and cloaking.

Applications for telecommunications, lasers and imaging systems are also explored.

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.
