Singular Higher Order Divergence-Conforming Bases of Additive Kind and Moments Method Applications to 3D Sharp-Wedge Structures (2008, methodology): “As already stated in [12], there is no interest in considering vertex singularity quadrilaterals since the only element-filler required to mesh in the neighborhood of the edge profile is the vertex singularity triangle.”
Fast Analysis of Large Antenna Arrays Using the Characteristic Basis Function Method and the Adaptive Cross Approximation Algorithm (2008, methodology): “To reduce the size of the matrix equation, one could employ subsectional basis functions of higher-order polynomials [6]; however, an even greater reduction in the number of unknowns can be achieved by employing macro basis/test functions.”
