Abstract :
The new discretized schemes of Mur´s absorbing boundary condition (ABC) based on finite difference frequency domain method has been presented in this paper. The analysis figures out that their numerical accuracy are second-order. Combining the new schemes with five-point format of Helmholtz equation to solve scattering problems, the numerical results show that the accuracy of numerical solution with the new schemes is higher than that with ordinary discretized scheme of Mur´s absorbing boundary condition.
