Abstract

The complex frequency shifted (CFS) perfectly matched layer (PML) has been proven to be more efficient in attenuating evanescent waves and reducing late-time reflections than the original PML. In this letter, the piecewise linear recursive convolution (PLRC) method is combined with the bilinear transform (BT) to implement the CFS-PML for unmagnetized plasma simulation. Compared to the original bilinear transform implementation, the computational cost of the PLRC CFS-PML is greatly reduced with the same absorbing performance.
