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

Figure 5

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