Seeing through smoke: modelling light scattering in irregular media

A T-Matrix method has been implemented and used to calculate the propagation properties for multiple types of irregular particles, which plays an important role in light propagation through turbid media such as smoke or dusty atmospheres.

Sumario:A T-Matrix method has been implemented and used to calculate the propagation properties for multiple types of irregular particles, which plays an important role in light propagation through turbid media such as smoke or dusty atmospheres. This method allows the calculation of the scattered field by non-spherical particles. A detailed description of those properties, such as the single scattering albedo and cross sections, as well as the comparison of these properties, has been performed for several orientations and angles of scattering, as well as for several concentrations of particles in the environment to compare the variation between them. The comparison has also been between spheroidal and spherical shapes since their properties of both scattering and absorption can be found by Mie theory. A continuation of this work will be performed to use in the future the T-Matrix method for performing light propagation in turbid media.
