✦ Synopsis

A non-re ecting boundary condition based on the Gauss ÿlter is employed for the determination of scattered potential governed by the Helmholtz equation. A ÿltering layer is used for closing inÿnite domain calculations. An expression for the re ection coe cient is derived and an optimal ÿltering layer is designed. Numerical results validate the performance of this method for unbounded wave guide problems.
