Broadband Stable Calderón-Preconditioned Vector-Potential-Only Integral Equations for PEC Scattering
Paul Olyslager, Hendrik Rogier, Kristof Cools
We propose a stabilized first-kind, Calderón preconditioned, vector-potential-only integral equation, for scattering at perfect electrical conductors. The method yields accurate lo…
