Cell Curvature and Far-Field Superconvergence in Numerical Solutions of Electromagnetic Integral Equations

Figure 9

Error in the SCS versus the average edge lengths in the models, for the same torus used in Figures 7 and 8. EFIE results are reported for a flat-faceted model used in conjunction with basis and test functions, a quadratic-curved model used with functions, and a cubic-curved model used with functions. Ideal asymptotic rates of , , and are shown for comparison.
