Abstract :
In this letter, Berenger´s perfectly matched layer (PML) absorbing boundary condition is presented for the efficient two-dimensional (2-D) finite-difference time-domain (FDTD) method with weighted Laguerre polynomials. Through adding a perturbation term, the huge sparse matrix equation is solved with a factorization-splitting scheme. To verify the validity of the proposed formulations, a numerical example of scattering from a 2-D rectangular conductor is given.
