Abstract

SummaryIn 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.
