Short summary
We propose a new boundary matched algorithm which can effectively combine the traditional first-order perfectly matched layer algorithm into the conventional-grid finite-difference scheme in a second-order system. This novel boundary method takes the advantages of the conventional-grid scheme and perfectly matched layer boundary conditions, making a good compromise of accuracy, excellent absorption effect, and high computational efficiency. Our method is also easy to implement.
