Research output: Contribution to journalConference articlepeer-review


This paper proves that a perfectly matched interface exists for linearized elastodynamics. This is easily done from the viewpoint of a stretched coordinate system. It also shows how the equations of motion could be split in the time domain in order to incorporate this effect in the time domain. This perfectly matched interface can be used to make perfectly matched layers as absorbers in numerical simulations to emulate an infinite region.
