Title: Plasmon resonance and electric field amplification of crossed gold nanorods
Author(s): Cortie, M. B.; Stokes, N.; McDonagh, A.
Abstract: Here we explore the unusual plasmon resonances of crossed gold nanorod structures of varying geometries. Using numerical simulations, we show that the resonances of simple rods are hybridized and blue-shifted in the composite structures and that these structures are surrounded by spatially extended and high intensity electric fields. This attribute suggests several potential uses for these shapes, for example as a nano-antenna for the generation of two-photon fluorescence.
