  • Abstract
    Discretized differential-forms basis functions were formulated and implemented for surface integral equation problems. Making the degrees of freedom scale invariant with element size leads to better conditioning of the system matrix for both electrostatic and frequency-domain scattering problems on meshes with a large variation in patch size.
