Near-field optics studies the behaviour of light fields in the vicinity of matter, where light is structured in propagating and evanescent fields. Near-field optical microscopy is the straightforward application of near-field optics.

Intrinsic features of the optical near field open a new frontier in optical science and technology by finally overcoming the diffraction limit to reach nanometric dimensions. But this book goes beyond near-field optical microscopy to cover local spectroscopy, nanoscale optical processing and storage, quantum near-field optics, and atom manipulation. Near-Field Nano/Atom Optics and Technology provides the first complete and systematically compiled account of the science and technology required to...
