Abstract :
In this letter, a scheme for a sparse global absorbing boundary condition (ABC) based on the boundary integral equation (BIE) and the wavelets technique is proposed for the finite-difference frequency-domain (FDFD) method. Numerical results show that this absorbing boundary condition has both the merits of the global ABC based on the BIE and the sparse characteristic.
