Keywords:

Plasmonics,Near-field intensity enhancement,Aberrations

Near-field intensity enhancement due to the plasmonic response of nanoparticles is investigated with the Mie theory and multipole expansion for an aberrated focusing system. Spherical aberration and defocusing are considered as an aberration in the focusing system.
