Abstract: | This paper calculates light scattering by a spherical water particle
containing densely packed inclusions at a visible wavelength
0.55 \mum by a combination of ray-tracing and Monte Carlo
techniques. While the individual reflection and refraction events at
the outer boundary of a sphere particle are considered by a
ray-tracing program, the Monte Carlo routine simulates internal
scattering processes. The main advantage of this method is that the
shape of the particle can be arbitrary, and multiple scattering can
be considered in the internal scattering processes. A dense-medium
light-scattering theory based on the introduction of the static
structure factor is used to calculate the phase function and
asymmetry parameters for densely packed inclusions. Numerical
results of the single scattering characteristics for a sphere
containing multiple densely packed inclusions are given. |
