| Div-conforming elements for the Surface Integral Equation are obtained by rotating curl-conforming bases used in the Finite Elements Method (FEM). The procedure maintains the Helmholtz decomposition for surface currents. This decomposition allows a frequency scaling of the system of equations which avoids the frequency breakdown. For addressing the problem of the singular term in the integral equation, we use the coordinate transformation from local space to a new space which, by means of the Jacobean, introduces a term that cancels out the singular behavior. The singularity cancellation is carried out directly on the local domain. The procedure is compatible with any order of curvature of the elements and invariant with the order of the bases functions; it is suitable for the treatment of the near-singularities. | |
