Unsplit Perfectly Matched Layer for a system of equations of dynamic elasticity theory

This paper presents an original approach to the construction of a Perfectly Matched Layer based on the Optimal Grids technique. This PML allows one to reach a suitable reduction of the reflections for all incident angles. The use of the Optimal Grids approach makes it possible to considerably decrease the computational time, because high accuracy of the solution can be reached using a small number of grid points.
