Figure 2

Wavelength dependence of elements (a) m21 and (b) m41 of the Mueller matrix measured at an angle of incidence θ = 20° on the elytron of the beetle C. chrysargyrea. (c) m21 as function of photon energy; the insert in (c) shows the labelling of maxima and minima with an index m. (d) Spectral dependence of m; the insert shows a fit to a linear dependence at low photon energies.
