abstract = {<p style="text-align: justify;">The scattering problem from time-harmonic waves by a Neumann type crack in $\mathbb{R}^2$ is considered. A PML technique is used for solving the problem with a bounded domain instead
of the infinite domain. A coupled finite-infinite element method is employed in the computation.
Because of the singularity of the solution, the infinite element method is used near the crack tip.
An error analysis is presented for the numerical approximation. The convergence order of the
method is higher than FEM&#39;s.</p>},
