Dlugach, J.M., and , 2006: Enhanced backscattering of polarized light: Effect of particle nonsphericity on the helicity-preserving enhancement factor. J. Quant. Spectrosc. Radiat. Transfer, 100, 115-121, doi:10.1016/j.jqsrt.2005.11.060.
We analyze theoretically the effect of particle nonsphericity on the backscattering enhancement factor ζhp in the helicity-preserving channel. Using numerically exact T-matrix and vector radiative-transfer codes, we have performed computations for optically semi-infinite homogeneous layers composed of polydisperse, randomly oriented oblate spheroids with the real part of the refractive index equal to 1.2, 1.4, and 1.6, the imaginary part of the refractive index equal to 0 and 0.01, various values of the equal-surface-area-sphere effective size parameter, and aspect ratios 1 ≤ ε ≤ 2. Our computations demonstrate that whereas for spheres ζhp ≡ 2, for spheroids the helicity-preserving enhancement factor can deviate quite significantly from the value 2. The magnitude of this deviation varies substantially with particle microphysical parameters and illumination geometry.
