In recent years there have been exciting developments in techniques for producing multilayered structures of different materials, often with thicknesses as small as only a few atomic layers. These artificial structures, known as superlattices, can either be grown with the layers stacked in an alternating fashion (the periodic case) or according to some other well-defined mathematical rule (the quasiperiodic case). This book describes research on the excitations (or wave-like behavior) of these materials, with emphasis on how the material properties are coupled to photons (the quanta of the light or the electromagnetic radiation) to produce "mixed� waves called polaritons.
�Clear and comprehensive account of polaritons in multilayered structures�Covers both periodic and quasiperiodic superlattices�Careful attention to theoretical developments and tools�Invaluable guide for researchers in this field�Shows developments from the basics to advanced topics
