PML Implementation for a New and Efficient 2-D Laguerre-Based FDTD Method

We previously introduced a new efficient algorithm for implementing the two-dimensional (2-D) Laguerre-based finite-difference time-domain (FDTD) method. In this letter, Berenger's perfectly matched layer (PML) absorbing boundary condition is presented for the new efficient 2-D Laguerre-based F...

Summary:We previously introduced a new efficient algorithm for implementing the two-dimensional (2-D) Laguerre-based finite-difference time-domain (FDTD) method. In this letter, Berenger's perfectly matched layer (PML) absorbing boundary condition is presented for the new efficient 2-D Laguerre-based FDTD method. The new formulations do not involve any nonphysical intermediate variables, while being more concise. The numerical example indicates that the presented PML has almost the same absorbing performance as the standard Laguerre-based PML.
