Abstract	The recently developed augmented electric field integral equation (A-EFIE) remedies the well-known low-frequency breakdown. However, it loses accuracy of current when applied to certain low-frequency applications like plane wave scattering. This paper addresses the low-frequency inaccuracy problem, and proposes a perturbation method as a remedy. A-EFIE with perturbation solves the same A-EFIE matrix system with updated right hand side vectors repeatedly to obtain the current and charge on different frequency orders as a perturbation series. This method does not require a search for the loop and tree basis, but the loop and tree currents can also be recovered. Numerical experiments validate the novel method.
