Abstract

An integral equation-based method for solving scattering by a 2-D lattice in 3-D using ML-FMA is proposed. The method utilizes fast evaluation of periodic Green's function in factorized form. The lattice summation approach is used to account for periodicity. The evaluation of the lattice constants is accelerated using Ewald summation. To compute the total field, image cells are separated into two categories (near and far lattice cells), where only far lattice cells make use of Ewald summation and near lattice cells are computed using conventional ML-FMA. This results in an O(N log N) method which can be easily implemented by extending existing ML-FMA codes.
