Mur Absorbing Boundary Condition for Three-Step 3-D LOD-FDTD Method

A consistent implementation of Mur first-order absorbing boundary condition (ABC) for three-step 3-D locally 1-D finite-difference time- domain (LOD-FDTD) method is presented. Numerical examples are included to validate the proposed scheme in comparison with Mur ABC for the standard FDTD and two other Mur ABC schemes for the LOD-FDTD. The numerical results illustrate that the proposed scheme can achieve good wave-absorbing capability.
