Solving Integral Equations on Piecewise Smooth Boundaries Using the RCIP Method: A Tutorial

Figure 13

Convergence for 𝑞 of (6) with 𝜌=𝜌₁ from (42). The curve Γ is as in (1), and theta = pi/2, npan = 11, and evec = 1. The reference value is taken as 𝑞=1.95243329423584. (a) Results from the inner product preserving scheme of Appendix D produced with demo10.m. (b) Results with RCIP according to (47) and (48) produced with demo10b.m.
