Abstract

Simulations and near-field measurements indicated that collective surface plasmons of silver nanoparticle clusters resulted in the super-resolution property of the AgOx-type super-resolution near-field structure. Randomly distributed metallic nanoparticle clusters transferred evanescent signals from subwavelength objects to propagating waves like a near-field probe and circumvented the diffraction limit.
