Near Field Optics And Nanoscopy

This text contains the most recent information on near field optics, namely the properties of the optical e.m. waves which propagate over distances shorter than the wavelength, taking into account the presence of small objects.

This book contains the most recent information on optical nanoscopy. Far-Field and Near-Field properties on e.m. waves are presented which illustrate how optical images can be obtained from sub-micron objects. Scanning Probe techniques and computer processing are covered here. An explanation is given on how propagating photons or evanescent waves can behave over distances shorter than the wavelength, taking into account the presence of small objects. Quantum tunneling of photons is explained comparatively with the electron mechanism. Technical details are given on photon tunneling microscopes. Typical results already obtained with these techniques are also described.
