title = "A Higher-Order Local Interpolation/Anterpolation Scheme of MLFMA for Computing Electromagnetic Scattering by Low RCS Objects",
abstract = "Realistic electromagnetic (EM) scattering problems often consist targets or structures aiming to reduce radar cross section (RCS) at some angle ranges, generating a challenge for the interpolation/anterpolation schemes of MLFMA. In this paper, we demonstrate that for a specially designed low RCS object, traditional local interpolation schemes using 4×4 samples cannot guarantee satisfactory accuracy. To remedy this, a higher-order Lagrangian interpolation scheme is proposed, whose performance is verified by numerical results. The proposed scheme has been used to calculate real-life EM scattering problem with coated cavities, nonconformal mesh grids and unknowns exceeding 48 million.",
