Abstract :
This paper proposes a complex frequency shifted PML absorbing boundary condition for the unconditionally stable finite difference time-domain method based on weighted Laguerre polynomials (WLPs). The method offers a number of advantages over the traditional implementations of the PML in the WLP-FDTD method. Numerical results show the CFS PML is effective.
