Abstract
—A conformal FDTD approach is developed to compute scattering from anisotropically coated bodies. Comparisons between the standard and conformal FDTDs are numerically carried out to demonstrate the advantages of the conformal FDTD. Scattering of anisotropic dielectric sphere is computed,and compared,with the analytical results to further validate the developed approach. Several new results of scattering by anisotropically coated bodies are also given in the paper.
