The low frequency breakdown problem has been studied through different methods. The near-field communication (NFC) antenna is electrical small and its operating frequency is 13.56 MHz. Full-wave analysis of this kind of antennas will cause instability. In this paper, A-phi method is presented, which uses the magnetic vector potential A and the scalar electric potential, to solve the low frequency radiation problems. Numerical simulations are performed to verify the ability in solving low frequency EM problems.
