    • The FDTD calculations are performed with a Drude dielectric function with parameters fitted to experimental data for gold.25 This fit accurately reproduces both the real and imaginary parts of the dielectric function of Au for wavelengths longer than 500 nm

    • A rigorous theoretical analysis of the scattering spectra of the nanostar would require a detailed modeling of the scattering geometry of the microscope and the effects of the substrate. Because the objective of the present paper is to provide a microscopic interpretation of the nature of the nanostar plasmon resonances, we focus on the computationally simpler extinction spectrum. The frequency and polarization dependence of the extinction and scattering spectra are known to be similar
