Abstract
Many particles in nature, such as ice crystals in cirrus clouds and airborne dust aerosol particles, are nonspherical with complex geometries. The scattering of polarized light by nonspherical particles is inevitably necessary for numerous disciplines, including polarimetric remote sensing. In this presentation, we report an advanced light-scattering computational capability, referred to as the synergistic light-scattering computational method, which is based on a combination of the invariant imbedding T-matrix method and the physical-geometric optics method. The former is applied to small to moderately large particles, whereas the latter is applicable to moderate to large particles. In particular, we illustrate the smooth transition of the results obtained with the two methods. Furthermore, we demonstrate the applications of the advanced light-scattering computational capability in polarimetric remote sensing.
