Figure 1: The geometric albedo and polarization P for randomly oriented BCCA particles consisting of optically dark submicron grains. The geometric albedo is also described using the corresponding values for S_{11}/k^{2} where S_{11} and k denote the (1,1) element of the scattering matrix S_{ij} and the wave number, respectively. Solid lines are the numerical results for the wavelength m and dotted lines are those for m. Dashed horizontal straight lines in the upper left corner of each lower panel are plotted to illustrate P=0. The number of constituentparticles in the aggregate is set to be N=64 (left panel), 128 (middle panel), or 256 (right panel). | |
