摘要

This paper presents a comparative analysis of the Ultra Weak Variational Formulation (UWVF) and the Generalized Finite Element Method (GFEM) approaches to compute the solution field generated by the scattering of an incident plane wave by a PEC obstacle. The aim is to show how the specific features of each approach can be used to improve the approximated solution. The results are supported by numerical experiment and a case study for a single simple geometry.
