Discrete dipole model of radiative transfer in dense granular layers
We have developed a numerical Regolith Radiative Transfer (RRT) model based on the Discrete-Dipole Approximation (DDA), which iteratively solves the exact wave equations for a granular target in response to an incident plane wave and mutual interactions between all component grains. We extend the traditional DDA approach in two ways: the DDA target is laterally replicated using periodic boundar...
متن کاملDiscrete-dipole approximation for scattering calculations
The discrete-dipole approximation (DDA) for scattering calculations, including the relationship between the DDA and other methods, is reviewed. Computational considerations, i.e., the use of complex-conjugate gradient algorithms and fast-Fourier-transform methods, are discussed. We test the accuracy of the DDA by using the DDA to compute scattering and absorption by isolated, homogeneous sphere...
متن کاملValidation of the community radiative transfer model
To validate the Community Radiative Transfer Model (CRTM) developed by the U.S. Joint Center for Satellite Data Assimilation (JCSDA), the discrete ordinate radiative transfer (DISORT) model and the line-by-line radiative transfer model (LBLRTM) are combined in order to provide a reference benchmark. Compared with the benchmark, the CRTM appears quite accurate for both clear sky and ice cloud ra...
متن کاملUsing a discrete dipole approximation to predict complete scattering of complicated metamaterials
We develop a numerical technique for simulating metamaterial electromagnetic response based on an adaptation of the discrete dipole approximation (DDA). Our approach reduces each constituent metamaterial element within the composite to a point dipole with electric and magnetic polarizabilities, rather than assuming a homogenized effective material. We first validate the approach by computing th...
متن کاملImprovements of the Discrete Dipole Approximation method
We report improvements in complex conjugate gradient algorithms applied to the discrete dipole approximation (DDA). It is shown that computational time is reduced by using the BiCGSTAB version of the CG algorithm, with diagonal left preconditioning.
