摘要: We study spontaneous emission enhancement of a two-level atomic emitter placed in dielectric medium near flnite-length cylindrical metal nanowire. calculate the dependence Purcell factor and normalized decay rate to continuous spectrum on nanowire radius for several transition wavelengths difierent orientations dipole moment. For particular wavelength we these quantities as well fl-factor distance from radius. The obtained results demonstrate that characteristics exhibit signiflcant difierences compared case an inflnite wire.
