Abstract :
In this paper, a perfectly matched layer (PML) implementation for an unconditionally stable finite-difference time-domain scheme based on weighted Laguerre polynomials(WLP-FDTD) in cylindrical coordinates is presented. A numerical example is introduced to validate the proposed formulations.
