Description
Summary:Large spatial frequency expansions for the source function, radiative flux, and intensity are obtained for an anisotropically scattering, two-dimensional, finite, cylindrical medium exposed to Bessel-varying collimated radiation. The scattering phase function is represented by a series of Legendre polynomials, and the scattering medium is finite in the z-direction and infinite in the r-direction. With these expansions, the single and double scattering approximations are obtained for a medium exposed to a Gaussian shaped laser beam. Results are presented for a wide range of particle sizes and refractive indexes. The back-scattered flux and intensity have a more complex behavior than the forward-scattered flux and intensity.
