Abstract :
Liao´s absorbing boundary condition (ABC) has been widely applied in the early finite difference time domain (FDTD) method, due to its advantages of simple form, good absorption effect and easy programming. In this paper, the frequency domain form of Liao´s ABC is derived and successfully applied in 2-D frequency domain finite difference (FDFD) algorithm. The numerical experiments validate that Liao´s ABC still shows excellent absorption effect in 2-D FDFD algorithm as it does in the 2-D FDTD algorithm.
