This paper describes a family of axisymmetric, spheroidal 'wave envelope' elements for modelling exterior wave problems. They are of variable radial order and can be used to represent steady and transient wave fields. The formulation is presented for the axisymmetric case using elements which are ba
## Abstract A fundamentalβsolutionβless boundary element method, the scaled boundary finiteβelement method, has been developed recently for exterior wave problems. In this method, only the boundary is discretized yielding a reduction of the spatial dimension by one, but no fundamental solution is n
