A fast direct solver for scattering from periodic structures with multiple material interfaces in two dimensions
Leslie Greengard, Kenneth L. Ho, June-Yub Lee
We present a new integral equation method for the calculation of two-dimensional scattering from periodic structures involving triple-points (multiple materials meeting at a single…
