FDTD-based comparison for isotropic excitation mechanism. (a) Polarization scan from − 90° to 90° for zigzag chains, linear chains, and randomly arranged AuNPs in discreet steps of 1°. (b) Calculated electric field profile for these three configurations at 0° polarization. (c) Similar field profiles for 90° polarization.
