Abstract :
In this letter, the numerical implementation of Mur´s absorbing boundary condition (Mur´s ABC) of second order in finite-difference time-domain (FDTD) is analyzed and studied in three-dimensional (3-D) scattering problems. Two new stable upwind finite-difference approximations of Mur´s ABC are presented and the later-time instability of FDTD with second-order Mur´s ABC in 3-D scattering problems is overcomed. Numerical results clearly exhibit the availability of the two upwind finite-difference approximations of Mur´s ABC
