Abstract
Ahierarchical quasi-Helmholtz decomposition, originally developed to address the dense-discretization breakdowns for the electric field integral equation, is applied together with an algebraic preconditioner to improve the convergence of the combined field integral equation in multiscale problems. The effectiveness of the proposed method is studied first on some simple examples; next, tests on real-life cases up to several hundreds of wavelengths show its good performance.File in questo prodotto:
