Abstract

The electric field interaction of hexagonal arrays of gold nanotriangles positioned on glass slides was studied using finite-difference time domain (FDTD) simulations. The length of the triangles (L = 100-300 nm), the irradiation wavelength (λ = 400-1100 nm), and the direction of the linearly polarized input field (either Px or Py) were the three variables considered in the calculation of the electric field spectra and the localized surface plasmons. The results show that the plasmonic properties of this array of nanostructures are susceptible to modification by changing any of these variables, and provide important information into the design of experiments where high electric field enhancement is required.
