Abstract

We propose a simple yet effective modification to significantly improve the accuracy of the finite-difference time-domain (FDTD) near-to-far-field (NTFF) transformation for calculating the backscattering of objects having strong forward-scattering lobes. In the modified approach, we merely omit integrating over the near-field plane located in the forward-scattering region. We validate the proposed approach via comparison with rigorous analytical solutions of plane waves scattered by single and multiple dielectric spheres.
