A finite element method is presented for solving three-dimensional radiation problems in time-harmonic acoustics. This is done by introducing a so-called ''Dirichlet-to-Neumann'' boundary condition on the outer boundary of the domain discretized with finite elements. This DtN boundary condition is a
