An efficient full-wave solver for eddy currents

An integral equation reformulation of the Maxwell transmission problem is presented. The uses techniques such as tuning free parameters and augmentation close-to-rank-deficient operators. It designed for eddy current regime works both surfaces genus 0 1. Well-conditioned systems field representations are obtained despite being ill-conditioned 1 due to presence Neumann eigenfields. Furthermore, it shown that these eigenfields, ordinary conductors in regime, different from classical eigenfields superconductors. Numerical examples, based on reformulation, give an unprecedented 13-digit accuracy transmitted scattered fields.
