Abstract

We have numerically analyzed the effect of geometrical parameters of circular, rhombic, and square nanostructure arrays when light fields are localized based on surface-enhanced nanoplasmonics. It was found that subdiffraction-limited field localization can be achieved using the nanostructures. We have also discussed various approaches to implement superresolution imaging systems using the obtained localized fields. The localized field can be used to implement colocalized light matter distribution with much enhanced sensitivity in surface plasmon resonance biosensor and more interestingly for super-resolution full-field microscopy.
