Simulated Optical Properties of Gold Nanocubes and Nanobars by Discrete Dipole Approximation
The absorption spectra for a gold nanocube and for a gold nanobar are calculated by using the Discrete Dipole Approximation (DDA). The results show the excitation of a single albeit broad surface plasmon (SP) band of the gold nanocube. The extinction cross section of the gold nanocube is dominated b...
