摘要
In this paper, the linear conforming finite element method for the one-dimensional Berenger's PML boundary is investigated and well-posedness of the given equation is discussed. Furthermore, optimal error estimates and stability in the L-2 or H-1-norm are derived under the assumption that h, h(2)omega(2) and h(2)omega(3) are sufficiently small, where h is the mesh size and omega denotes a fixed frequency. Numerical examples are presented to validate the theoretical error bounds.
