Paper Abstract
Cascaded optical field enhancement in coupled plasmonic nanostructures has attracted significant attention because of
field enhancement factors that dramatically exceed those observed in isolated nanostructures. While previous studies
demonstrated the existence of cascaded enhancement, little work has been done to identify the requirements for
achieving maximum field enhancement. Here, we investigate cascaded field enhancement in silver nanosphere dimers as
a function of volume ratio and center-to-center separation, and show the requirements for achieving the ultimate
cascading limit in nanoparticle dimers. We observe field enhancements that are a factor 75 larger than observed in
isolated silver nanoparticles.
