Figure 2

Relative polarizationsderived from DDA-based simulations of a prolate Ag spheroid with semiaxes a = 10 nm and c = 40 nm; the simulations employ uncorrected CM polarizabilities. Each subunit is represented by a square colored according to the relative polarization scale shown at the bottom of the figure. The upper panel gives the results for a spheroid modeled using N = 6041 subunits of edge length d = 1.405 nm; the lower panel gives the results for N = 24679 subunits of edge length d = 0.879 nm. Only subunits with x = 0, y ≥ 0, and z ≥ 0 are shown
