Figure 4
The results of the inverse analysis on the spectral scattering Mueller matrices M(λ) of the Au nanorod (corresponding to Fig. 3).
(a) The Mueller matrix-derived wavelength variation of the linear retardance δ(λ) (right axis, red dotted line) and linear diattenuation d(λ) (left axis, blue solid line) parameters. The inset shows wavelength variation of the decomposition-derived depolarization coefficient Δ(λ). (b) The corresponding theoretically computed d(λ) and δ(λ) parameters for a preferentially oriented similar Au nanorod, under plane wave excitation. (c) The spectral line shapes of the scattered intensity Idet(λ) for excitation with −45° linear polarization (M) and subsequent detection using +45° (P) analyzer basis (blue solid line) and without any analyzer (polarization-blind detection, black dotted line). The strength of the interference signal (Iint(λ)) is displayed in the inset, wherein a cartoon of the polarization state generator and the analyzer is also displayed.
