A Nitsche-based nonconforming hp-FE/BE coupling on unstructured non-matching meshes is shown to be stable above an explicit threshold with a priori error estimates for quasi-uniform and geometrically refined discretizations.
A preconditioning technique for the shifted Helmholtz operator stabilizes EFIE iterative solvers across multiple frequency and discretization regimes, enabling quasi-linear complexity.
