title: The strong localization of surface plasmon polariton on a metal-coated tip of optical fiber.
abstract: It is shown that during the propagation of surface plasmon polariton (SPP) on a metal-coated tip of an optical fiber its wavelength essentially decreases and wave fields anomalously increase. Dependence of a degree of localization of SPP on sharpness of the structure and width of the metal layer is defined. The received results can be used to increase the resolution of scanning optical microscope.
