  The Generalized Method of Moments (GMM) is a partition of unity based
technique for solving electromagnetic and acoustic boundary integral equations.
Past work on the GMM for electromagnetics was confined to geometries modeled by
piecewise flat tessellations and suffered from spurious internal line charges.
In the present article, we redesign the GMM scheme and demonstrate its ability
to model scattering from PEC scatterers composed of mixtures of smooth and
non-smooth geometrical features. Furthermore, we demonstrate that because the
partition of unity provides function and effective geometrical continuity
between patches, the GMM permits mixtures of local geometry descriptions and
approximation function spaces with significantly more freedom than traditional
moment methods.
