Abstract :
A perfectly matched layer (PML) with complex-frequency-shifted (CFS) constitutive parameters is introduced to the alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method in cylindrical grids. The new CFS-PML is based on complex stretching methodology and implemented using bilinear transform. Numerical results show the effectiveness of the proposed implementation.
