HelmPole- A finite element solver for scattering problems on unbounded domains: Implementation based on PML ZIB-Report 03-38 (November 2003) The solution of scattering problems described by the Helmholtz equation on un-bounded domains is of importance for a wide variety of applications, for example in electromagnetics and acoustics. An implementation of a solver for scattering problems based on the programming language Matlab is introduced. The solver relies on the finite-element-method and on the perfectly-matched-layer-method, which allows for the simulation of scattering problems on complex geometries surrounded by inhomogeneous exterior domains. This report gives a number of detailed examples and can be understood as a user manual to the freely accessibl
