Resumo Inglês:
In this paper, we present a quantitative comparison of
circular and triangular gold nanodisks with the same length and
thickness. The method of moments is used to solve numerically the
scattering problem. With this model, we investigate the spatial near
field distribution, spectral response, far field diagrams, and
bandwidth wavelength of these particles. Our results show that the
resonant wavelength and the near field enhancement and
confinement of the triangular particle are larger than those for the
circular particle, but the resonance bandwidth and scattering cross
section of the triangular particle are smaller.
