Papers presented at the NATO Advanced Research Workshop on Localization and Propagation of Classical Waves in Random and Periodic Media held in Heraklion, Crete, May 1992. The volume summarizes the state-of-the-art of the photonic band gap and classical localization areas of research, with the collection of papers roughly balanced between theory and experiment. It contains chapters that present latest research results as well as ones that review a particular field. The volume is divided into three parts representing the topics discussed at the workshop: localization, diffusion, and correlation; photonic band gaps; and wave propagation in random media.
