Abstract :
In this paper, we demonstrate the manner in which one can incorporate basis functions in vector generalized finite element method (GFEM). This method is used to analyze scattering from a wedge with varying angles and examine convergence of the proposed method. We compare the results obtained using this solver against classical FEM. Comparison with FEM with singular basis function is presented at the conference
