WebFeb 2, 2024 · In this paper, we consider a two-dimensional acoustic wave equation in an unbounded domain and introduce a modified model of the classical un-split perfectly matched layer (PML). We apply a regularization technique to a lower order regularity term employed in the auxiliary variable in the classical PML model. Webcomputation, the PML method has two opposite constrains: – At lower frequencies, the PML layer should be thick enough to absorb acoustics with longer wavelength – At higher frequencies, the element size within the PML should be small enough to capture the shorter wavelengths • APML automates the PML mesh creation, twenty four store
