Characterization and Integration of the Singular Test Integrals in the Method-of-Moments Implementation of the Electric-Field Integral Equation
Brian A. Freno, William A. Johnson, Brian F. Zinser +3
In this paper, we characterize the logarithmic singularities arising in the method of moments from the Green's function in integrals over the test domain, and we use two approaches…

Symmetric Triangle Quadrature Rules for Arbitrary Functions
Brian A. Freno, William A. Johnson, Brian F. Zinser +1
Despite extensive research on symmetric polynomial quadrature rules for triangles, as well as approaches to their calculation, few studies have focused on non-polynomial functions,…
