Abstract:

The equations for calculation of the amplitude and cross section of light scattering by optically "soft" hexagonal cylindrical particles of finite length in the Rayleigh-Gans-Debye approximation are obtained. Numerical results on the light scattering phase function (or the element f11 of the scattering phase matrix) for infinitely long cylinder (rigorous solution) and for finite circular and hexagonal cylinders in the Rayleigh-Gans-Debye approximation are compared. The approximate equations for the light scattering cross section of circular and hexagonal cylinders in Rayleigh-Gans-Debye approximation for small diffraction parameters ka < 1, kH < 1 (where k, H, a are the wavenumber, height, and radius of the cylinder, respectively) are obtained.
