Abstract

We investigate the effect on transmission of p-polarized light of the excitation of plasmons of metallic nanocylinders, placed at the exit of subwavelength slits. Morphology-dependent resonaces of the aperture may then be excited, thus leading to supertransmission. The possible enhancement of transmittance is investigated by working out appropriate choices of the geometrical parameters and illumination. Additionally, we study conditions in which supertransmitted light may propagate through sets of metallic cylinders with excited plasmons, in front of either one slit or placed in front of a periodic array of slits. We find that the concentration and intensity of the transmitted field is mainly governed by both the material and geometrical configurations of the particle sets.
