Absorbing boundary condition for efficient 2-D WLP-FDTD method based on domain decomposition technique

We previously introduced a new efficient algorithm for the 2-D WLP-FDTD method based on domain decomposition technique. In this letter, the absorbing boundary conditions (PLM, UPML) have been applied in the method above. The numerical example indicates that the PML/UPML based on domain decomposition technique has almost the same absorbing performance as the efficient Laguerre-based ones.
