| Abstract: | In this paper, we explore a combination of the reciprocal absorbing boundary condition with perfectly matched discrete layers for the time-domain analysis of wave motion in the full plane. Coupling of these absorbing boundaries leads to solutions for out-of-plane as well as in-plane excitations of the full plane. Together with numerical transient simulations, harmonic analysis is also carried out for the purpose of verifying the results by comparing with available exact frequency-domain solutions. The proposed combination is investigated through several numerical examples, which demonstrate its accuracy and efficiency. |
