Abstract: (1824 Views)
We investigate the behavior of the plasmonic modes excited by the nanoholes structures. For this purpose, we have designed a vertical nanohole structure that realizes the different plasmonic fields maxima when excited with different incident wavelengths. After examining the effect of the substrate material and nanohole dimensions on the excited plasmonic modes, we have shown the realization of the superposition effect and displacement of the maximum field intensity along the depth of the double-step cylindrical holes. Simulations show that the proposed structure can be used as a plasmonic manipulation system, by well adjusting the incident laser beam, to move nanoparticles along the depth of the proposed nanoholes.
