Broadband Stable Calder\'on-Preconditioned Vector-Potential-Only Integral Equations for PEC Scattering

We propose a stabilized first-kind, Calder\'on preconditioned, vector-potential-only integral equation, for scattering at perfect electrical conductors. The method yields accurate low-frequency results for both the vector and the scalar potential, where the scalar potential is computed using the Lorenz gauge in the pos...
