A Late-Time Stable Scalar-Only Integral Equation for the Modelling of Transient Scattering by Perfect Conductors
Scattering of time-harmonic Maxwell fields by perfect conductors is most commonly modelled by the electric field integral equation. This equations can be rendered numerically stable in both the low frequency and dense grid regimes using a combination of Helmholtz splitting and rescaling using quasi-Helmholtz projectors...
