Abstract
In this study, to quantify the accuracy of the finite element method, it is useful to compare results obtained using the finite element method for scattering by an isotropic sphere to the exact results obtained using Mie theory. To compute the Mie theory results presented below, we have employed the BHMIE computer code provided by Bohren and Huffman, with additional code introduced for computation of the asymmetry parameter. In this computational approach, series expansions are performed to compute the scattering cross section and asymmetry parameter at far field.
