Abstract
Various optical properties originated from the surface plasmon resonance have been much studied, as the example of extraordinary optical transmission (EOT) arising in the metallic thin film with a nano-hole array (NHA). In the analytical chemistry, these phenomena can be applied to the sensors for viruses and bacteria based on the peak shift caused by the change in surrounding refractive index. We have clarified that the amount of EOT peak shift can be enhanced by designing the surface structure of NHA with the random nano-spikes. The results indicate the two cases that the peak shift is enhanced with and without the EOT, which leads to the understanding of the applicable range of random NHA design.
