“…The solution to the EFIE is typically effected by using method of moments (MoM) wherein surface current is represented by a set of vector basis functions, say the Rao-Wilton-Glisson basis functions [30] which are equivalent to the lowest order Raviart-Thomas functions [31]. Alternatives to this approach has been a topic of significant recent interest; these include using generalized method of moments (GMM) [32], [33], subdivision surfaces [27], discontinuous basis set [34] , and more recently, Debye sources [19]. All the aforementioned methods try to bring features into modeling electromagnetic scattering; but a common thread that ties GMM, MoM on subdivision surfaces, and Debye sources is the use of surface Helmholtz decomposition.…”

“…However, generating conformal discretizations for engineering system-level simulations is far from trivial, as the complexity of modern engineering applications increases at a fast pace. Among the previous works addressing the above mentioned deficiencies, we mention recent works [28][29][30][31][32].…”

“…Consistent with the central theme of the GMM framework, we develop a scheme that permits different orders of polynomials or different functions to be defined on adjacent patches. It has been shown, for integral equation based solvers 41,42 , that this can be achieved using a …”

“…The basis functions developed within this framework are continuous across domains and, as a result, do not need additional constraints to ensure continuity. The authors have recently developed methods that extend this idea to surface integral equations as applied to electromagnetics 41,42 , and have demonstrated convergence, well conditioned properties as well as application analysis of scattering from the range of targets. Unfortunately, this method still relies on an underlying tessellation.…”
