Abstract
When solving open-region scattering problems using the finite element method, the infinite region exterior to the scatterer must be truncated with an artificial boundary to limit the number of unknown. As a result, a boundary condition must be created at this boundary for a unique finite element solution. Two classes of such boundary conditions have been developed and used extensively in the finite element solution of scattering problems. The first class is derived from the boundary integral equations involving Green's functions. The second class is derived from the differential wave equations.
