An Efficient FDTD Implementation of the CFS-PML Based on the ADE Method and its Validation along with the PLRC method in Dispersive Media
Based on the stretched coordinate perfectly matched layer (SC-PML) formulations and the auxiliary differential equation (ADE) method,an efficient implementation of the complex frequency shifted PML (CFS-PML) is proposed for truncating the finite-difference time-domain (FDTD) lattices.For simulating dispersive media,the piecewise-linear recursive convolution (PLRC) method is incorporated into the FDTD update scheme.A numerical validation of the proposed formulations is given through a radiation problemInthreedimensional dispersive media. It is shownInthe numerical test that the proposed PML formulations with CFS scheme are efficientInattenuating of low-frequency and evanescent waves and reducing late-time reflections,and also hold better absorbing performance than the convolutional PML (CPML).
