Implementation of some iterative matrix solvers in simulation of the wave propagation problem using the time-harmonic finite difference algorithm


In this paper, the formulation of two-dimensional finite difference frequency domain (FDFD) for heterogeneous and lossy materials is presented. But the main attention is focus on the efficient formulation of the matrix solver. Contemporary, the numerical models are consisted of a large-scale sparse complex matrix, therefore the specific formulation of the… (More)
