text: We model negative polarization, which is observed for planetary regoliths
at backscattering, solving a full wave problem of light scattering with a numerically
exact Discontinuous Galerkin Time Domain (DGTD) method. Pieces of layers with
the bulk packing density of particles close to 0.5 are used. The model particles
are highly absorbing and have irregular shapes and sizes larger than the wavelength
of light. This represents a realistic analog of low-albedo planetary regoliths.
Our simulations confirm coherent backscattering mechanism of the origin of negative
polarization. We show that angular profiles of polarization are stabilized if
the number of particles in a layer piece becomes larger than ten. This allows
application of our approach to the negative polarization modeling for planetary
regoliths.

text: 'We review our results of numerical simulations of light scattering from different
systems of densely packed irregular particles. We consider spherical clusters,
thick layers and monolayers with realistic topologies and dimensions much larger
than the wavelength of light. The maximum bulk packing density of clusters is
0.5. A numerically exact solution of the electromagnetic problem is obtained using
the Discontinuous Galerkin Time Domain method and with application of high- performance
computing. We show that high packing density causes light localization in such
structures which makes an impact on the opposition phenomena: backscattering intensity
surge and negative linear polarization feature. Diffuse multiple scattering is
significantly reduced in the case of non-absorbing particles and near-field interaction
results in a percolation-like light transport determined by the topology of the
medium. With this the negative polarization feature caused by single scattering
gets enhanced if compared to lower density samples. We also confirm coherent double
scattering mechanism of negative polarization for light scattered from dense absorbing
slabs. In this case convergent result for the scattering angle polarization dependency
at backscattering can be obtained for a layer of just a few tens of particles
if they are larger than the wavelength.'

text: We study a double-scattering coherent mechanism of negative polarization (NP)
near opposition that is observed for powder-like surfaces. The problem is solved
numerically for absorbing structures with irregular constituents, cubes, spheres,
and ellipsoids larger than the wavelength of incident light. Our simulations show
that double scattering between two random irregular particles shows weak NP. Adding
one more particle significantly increases the relative contribution of double
scattering which enhances NP. Simulations with regular shapes and controlled geometric
parameters show that the interference mechanism is sensitive to the geometry of
the scattering system and can also result in no polarization or even strong enhancement
of positive polarization at backscattering.

text: We numerically simulate multiple light scattering in discrete disordered media
represented by large clusters of irregular non-absorbing particles. The packing
density of clusters is 0.5. With such conditions diffuse scattering is significantly
reduced and light transport follows propagation channels that are determined by
the particle size and topology of the medium. This kind of localization produces
coherent backscattering intensity surge and enhanced negative polarization branch
if compared to lower density samples.

text: We consider light scattering from a new type of model particle whose shape
is represented in the form of a generalized ellipsoid having N foci, where N is
greater than two. Such particles can be convex as well as concave. We use the
geometrical optics approximation to study the light scattering from 3-foci particles.
Non-zero elements of the scattering matrix are calculated for ensembles of randomly
oriented independent transparent particles, m = n + i0. Several internal reflection
orders are considered separately. It was found that the transmission-transmission
(TT) and transmission-reflectance-transmission (TRT) components dominate in the
formation of intensity of scattered light at large and small phase angles, respectively.
We found a significant role of the total internal reflections of the TRT in the
middle portion of the phase angle range. The main factors in the formation of
positive linear polarization are the R and TRT component. The TT component is
responsible for the formation of negative polarization branch at large phase angles.

text: "We study the dependence of the intensity and linear polarization of light
scattered by isolated particles with the compact\r\nirregular shape on their size
using the discontinuous Galerkin time domain numerical method. The size parameter
of particles varies in the range of X = 10 to 150, and the complex refractive
index is m = 1.5 + 0i. Our results show\r\nthat the backscattering negative polarization
branch weakens monotonously, but does not disappear at large sizes, up to the
geometrical optics regime, and can be simulated without accounting for wave effects.
The intensity backscattering surge becomes narrower with increasing particle size.
For X = 150, the surge width is several degrees."

text: We numerically simulate the circular polarization ratio of the radar signal
backscattered from a large-grain cometary coma and compare the simulation results
with the radar measurements for seven comets. We apply the discrete dipole approximation
method and a model of random irregular particles. Our results confirm water ice
composition of the cm-sized chunks detected by the NASA Deep Impact space probe
in the vicinity of the nucleus of Comet 103P/Hartley 2. The index of the power-law
size distribution in this case can be constrained to the range n ≈ 3.3–4.3. For
the other considered comets the circular polarization ratio can be reproduced
with variations of the power index between 2 and 5.

text: 'The problem of light scattering by ice crystals of cirrus clouds is considered
in the case of a hexagonal ice plate with different distributions over crystal
orientations. The physical-optics approximation based on (E, M)-diffraction theory
is compared with two exact numerical methods: the finite difference time domain
(FDTD) and the discontinuous Galerkin time domain (DGTD) in order to estimate
its accuracy and limits of applicability. It is shown that the accuracy of the
physical-optics approximation is estimated as 95% for the averaged backscattering
Mueller matrix for particles with size parameter more than 120. Furthermore, the
simple expression that allows one to estimate the minimal number of particle orientations
required for appropriate spatial averaging has been derived.'

text: In the problem of light scattering by ice crystals of cirrus clouds, two exact
methods (FDTD – finite difference time domain and DGTD – discontinuous Galerkin
time domain) and the physical-optics approximation are used for numerical calculations
of the Mueller matrix in the case of ice hexagonal plates and columns. It is shown
that for the crystals larger than 10 μm at the wavelength of 0.532 μm the exact
methods and physical-optics approximation closely agreed within three diffraction
fringes about the centers of the diffraction patterns. As a result, in the case
of random orientation of these crystals, the physical-optics approximation provides
accuracy 95% for the averaged Mueller matrix.

text: "We simulate light scattering by random irregular particles that have dimensions
much larger than the wavelength of incident light at the size parameter of \U0001D44B=200
using the discontinuous Galerkin time domain method. A comparison of the DGTD
solution for smoothly faceted particles with that obtained with a geometric optics
model shows good agreement for the scattering angle curves of intensity and polarization.
If a wavelength-scale surface roughness is introduced, diffuse scattering at rough
interface results in smooth and featureless curves for all scattering matrix elements
which is consistent with the laboratory measurements of real samples."

text: The physical optics approximations are derived from the Maxwell equations.
The scattered field equations by Kirchhoff, Stratton-Chu, Kottler and Franz are
compared and discussed. It is shown that in the case of faceted particles, these
equations reduce to a sum of the diffraction integrals, where every diffraction
integral is associated with one plane–parallel optical beam leaving a particle
facet. In the far zone, these diffraction integrals correspond to the Fraunhofer
diffraction patterns. The paper discusses the E-, M- and (E, M)-diffraction theories
as applied to ice crystals of cirrus clouds. The comparison to the exact solution
obtained by the discontinuous Galerkin time domain method shows that the Kirchhoff
diffraction theory is preferable.
