Abstract
An unconditionally stable numerical method combined with R-FDTD for the scattering problems is proposed. The marching-on in time method as in the FDTD scheme is replaced by a marching-on in order method based on weighted Laguerre polynomials. The divergence relationship is also used in the proposed method, which leads to a more memory efficient formulation. To verify the accuracy and the efficiency of the proposed method, we compare the results of the conventional FDTD method with the proposed method
