Abstract

Effective formulations of the complex frequency-shifted perfectly matched layer (CFS-PML) based on the two-dimensional (2-D) TE phi body of revolution finite-difference time-domain (BOR-FDTD), named as the BOR-CFS-PML, are proposed to truncate the Drude media. The auxiliary differential equation (ADE) method and the trapezoidal recursive convolution (TRC) method are applied to the implementation of the BOR-CFS-PML. The proposed formulations have good performance in attenuating low-frequency evanescent waves and reducing late-time reflections. A numerical test is provided to validate the effectiveness of the proposed algorithm.
