Two-stage SC + Finite Difference (FD) procedures have been proposed since a long time to solve electrostatic and magnetostatic field plane problems in case of inhomogeneous dielectric materials. This had allowed to overcome accuracy problems caused by convex corners in the domain boundary and relevant field singularities, and to apply FD solvers in rectangular domains. In this paper, compound procedures...
Both conformal mapping via Schwarz–Christoffel (SC) formulas and finite element methods (FEM) can provide accurate results in analyzing 2-D electric or magnetic fields. In the presence of curved boundaries with small radius of curvature, the first are normally constrained to introduce piecewise straight lines. The original contribution of this paper consists of presenting a reliable but simple procedure...
