Photonic Crystals

"This book is destined to become the classic textbook in the area. It gathers together the fundamental concepts and tools relevant to photonic crystals and presents them with exceptional clarity. I genuinely enjoyed reading it."--Maryanne Large, University of Sydney
"An excellent textbook to be used in physics, chemistry, and engineering. The revised edition of Photonic Crystals fills the gap between the layperson and the expert reader."--Costas M. Soukoulis, Iowa State University
