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