Abstract :
A new implementation of perfectly matched layer (PML) using recursive convolution technique is introduced for an alternating direction implicit (ADI) finite-difference time-domain (FDTD) method. Numerical results show that, compared with its analogue suggested earlier, the new method improves the reflection error by 30 dB even for large time step sizes.
