Abstract
Magnetic vector potential (MVP) formulations are widely used in low-frequency computational electromagnetics of finite element method (FEM). How to impose the gauge condition properly to ensure the uniqueness of the MVP is a key problem for researchers. Traditional Coulomb gauged formulation using penalty technique is not feasible for edge elements since the divergence of the edge element basis function is zero within each element. In this paper, a novel MVP formulation with Coulomb Gauge for full-wave Maxwell equations using edge elements is proposed in frequency domain. The proposed formulation is stable for all frequencies. Numerical examples are computed using the proposed MVP formulation, which is very promising in further engineering applications.
