N2 - A fast direct solver based on the generalized Debye sources for problems of electromagnetic scattering by conducting bodies has been developed. The fields are represented via two vector and two scalar potentials, which, in turn, are expressed via two fictitious charge densities. This approach reduces to simultaneously solving two Fredholm integral equations for scalar quantities and two Poisson's equations with the surface Laplacian. It is free from spurious resonances and the low-frequency breakdown. The proposed generalized Debye sources-based direct solver uses the hierarchical interpolation grids of the multilevel non-uniform grid (MLNG) algorithm and a rank-revealing solution scheme.
