Fig. 4.From: Polarimetric technique to study (pre)biological organics in cosmic dust and planetary aerosolsDependence of circular polarization on the number of the monomers as a function of (a) wavelength and (b) phase angle. The number of monomers, each of radius 0.1 micron, is specified in the legend. Spectral dependence, (a), is shown at phase angle 90°. Wavelength for (b) is 660 nm.Back to article page
