Nonlocal evanescent modes in near field optics — •Alfons Stahlhofen — Inst. f. Physik, Rheinau 1, D-56075 Koblenz

Near field optics is governed by the physics of evanescent waves. The systematic exploration of evanescent modes started blooming with the advent of photon scanning tunneling microscopy. Despite the comprehensive numerical studies of evanescent modes done in near field optics, some basic physical facts resulting from the nonlocal character of evanescent modes, made out of virtual photons, apparently escaped notice so far. The nonlocal character of evanescent modes is illustrated and some consequences for prominent systems of near field optics are elucidated
