Abstract
The quad-curl problem arises from the inverse electromagnetic scattering theory and magnetohydrodynamics. In this paper, a weak Galerkin method is proposed using the curl-conforming Nédélec elements. On one hand, the method avoids the construction of the curl–curl conforming elements and thus solves a smaller linear system. On the other hand, it is much simpler than the case of using the fully discontinuous elements. For polynomial spaces of order k, error estimates of \(O(h^{k-1})\) in the energy norm and of \(O(h^{k})\) in the \(H(\text {curl})\) norm are established, which are validated by the numerical examples.
