Abstract :
An improvement of the split-field perfectly-matched layer (PML) medium for the envelope alternating-direction implicit (ADI) finite-difference time-domain (FDTD) method is proposed. Comparing with the traditional PML, the performance of the proposed PML for the envelope ADI-FDTD method maintains good absorption even for large temporal increment.
