## Abstract Consider a twoβdimensional plane wave transverse magnetic mode scattering from a perfectly electric conducting ground plane. Let the ground plane be of infinite extent and comprise two regions, a near field and a far field. In the far field, let the ground plane be flat and let us choos

β¦ Synopsis
Special types of boundary elements are discussed which can be used for the modelling of surfaces which extend to infinity. The theoretical background and details of implementation are discussed. On test examples it is shown that the elements perform extremely well even for cases in which they are located close to the area of interest. A practical application of the use of the elements for the modelling of mining excavations is given.

A new, improved infinite element based on mapping is proposed for modelling unbounded domain problems. Mapping has previously been used in such problems, not only for the entire domain, but also for the infinite element itself. The novelty of the present approach is the simplicity of the mapping, an
A common method for numerically approximating two-point parabolic boundary value problems of the form u, = L[u] +f(u) defined on the semi-infinite strip S = [0, 11 X [0, 00) is to first discretize the spatial operator in the differential equation and then solve for the time evolution. Such an approa
