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

Figure 7

Error in the SCS versus number of unknowns for a torus with ka = 3 and kb = 6, obtained from the MFIE with Galerkin testing. 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.
