Abstract
The polarized light-scattering from a random assembly of anisotropic rods was formulated in three dimensions so that the size of the rod was finite in length as well as in radius, and that the principal optical axes of scattering elements were oriented within the rod with given polar and azimuthal angles to the rod axis.The Hv and Vv scattering patterns were calculated by fixing either the length or radius of the rod as several times larger than the wave length, but, in contrast, varying either the radius or length of the rod from infinitesimally thin to the same order as the fixed length or radius, respectively, to include the infinitesimally thin rod or disc as extreme.The Hv and Vv patterns degenerated, in general, into small scattering angles with the increasing of the radius or thickness of the infinitesimally thin rod or disc. The Hv patterns changed from ×-type to +-type patterns with the variations of the inclined angle of the scattering elements from zero to 50°, irrespective of the rod and disc models. On the other hand, however, the Vv patterns changed from the horizontal dumb-bell type to the vertical type for the rod model and from the vertical dumb-bell type to the horizontaltype for the disc model, both with the variations of the inclined angle from zero to 90°.
