Abstract

We analyze numerically the localized surface plasmon resonance (LSPR) frequencies of coupled metal nanorods using discrete dipole approximation (DDA) and finite element method (FEM). The two configurations of identical nanorods are considered: end-to-end and side-by-side. Dependence of LSPR frequencies on the interparticle distance is determined by DDA. The latter for the case of large separations agrees with the result of approximate analytical method developed earlier for single metal nanorods. Distributions of electric near-fields of nanorods as well as enhancement factors at hot spots for both configurations are calculated by FEM.
